General
  1. What is Zmanda Cloud Backup (ZCB)?

    Zmanda Cloud Backup (ZCB) is a comprehensive backup solution for small and medium businesses that need disaster recovery for their Windows Servers, Desktops and Laptops and applications such as Microsoft Exchange and MS SQL Server.

    ZCB has an open architecture which puts you in control of your backup data, storage location and backup policies. It backs up to highly robust storage cloud of Amazon S3 to ensure your backed up data is safe and secure at all times.

  2. Why cloud backup?

    There are several reasons. First and perhaps the most important is data safety. The popular backup media such as magnetic tapes, hard disks, DVDs are error prone and have higher failure rates. And of course, keeping your backup data at your office location doesn't protect you from unfortunate disasters such as cyclones, floods, etc.

    Second important reason is automation and reliability of backups. With cloud backup, backups happen automatically in background and require no manual intervention at all.

    Cost effectiveness, round-the-clock availability and easy access from anywhere are some other important reasons.

  3. Would uploading/downloading data to cloud be slow?

    Unlike many online backup solutions which use their owned datacenters in one or two locations, ZCB leverages the distributed cloud architecture of Amazon S3. This allows you to choose the specific cloud datacenter which is closest/faster for you.

    ZCB is network resilient and intelligently attempts to resume upload jobs in case of network connection outages. In addition, ZCB can adapt to best suit your internet connection. ZCB supports multithreaded uploads/downloads, which means it opens multiple parallel connections to the cloud. Depending on your CPU, memory and bandwidth resources, you can configure ZCB to use specific number of threads.

    Also, you can change the block size of the transfers to and from cloud, based on the quality of your Internet bandwidth.

    For more details, please see our help article.

Features and Compatibility
  1. Is there a web-interface to check by cloud usage and backup reports?

    Yes, please look at our ZCB Global Dashboard web-application. You can use this application to monitor the activity of your multiple ZCB subscriptions a single-login system.

  2. Which versions of Windows can you backup?

    ZCB supports Windows 8, 7, Vista, XP, Server 2003 / 2008 /2012 and SBS Server 2008 / 2011.

  3. How does ZCB backup SQL Server databases?

    ZCB supports efficient Full, Differential and Incremental (Log) backups of SQL Server databases. Full backups are VSS snapshot based while Differential and Incremental backups are SQL VDI based. Using incremental (Log) backups, you can achieve Continuous Data Protection (CDP) of your SQL server databases.

  4. How does ZCB backup Exchange Server databases?

    ZCB supports VSS snapshot based Full, Differential (Log) and Incremental (Log) backups of Exchange Servers. To recover individual mailboxes, you can use by using native Microsoft tools. Please see this help article for details.

  5. How does ZCB backup Hyper-V Servers?

    ZCB supports VSS snapshot based Full backups of specific guest VMs. You can restore a VM to the original location or a different Hyper V server.

  6. Can ZCB backup other operating systems such as Linux?

    No. But there is a workaround. ZCB supports backing up of network mapped drives. So if you wish to backup data on your Linux servers, you can map them on ZCB machines using sharing protocols such as Samba.

    However, if you need a native cloud backup support for heterogeneous systems such as Linux, Windows, Mac, Solaris, etc. we suggest you consider Amanda Enterprise our open source network backup product which provides an option to backup to Amazon S3 or Google Cloud Storage clouds.

  7. Can I restore deleted files? Do you support versioning so that I can restore files from an earlier backup run?

    Each ZCB backup has a unique timestamp and can be used to restore all the data which existed at the time of running a backup. The future actions such as modification or deletion of files don't touch the earlier backups at all. So as long as the backup run data hasn't expired (as per your configured retention policy), you would be able to retrieve older versions of your files.

    This means that unlike many other backup products which enforce a time period or number of versions to preserve file history, ZCB offers you a complete control on this feature. You can increase/decrease the backup frequency to control versioning and you can configure the data retention policy to control the number of days your deleted/modified data will be available for restore.

  8. What options do I have to store my backup data? Do you support network drives?

    ZCB offers you the complete flexibility about storage media. You can choose to keep your data only on cloud storage, only on local disk storage (local disk, external hard disk or network mapped drive) or both for high redundancy and faster local restores.

    back to top
  9. What about data retention?

    ZCB offers two types of retention policies. The first type allows you to specify number of backup cycles you want to retain. A backup cycle is 1 Full backup + any differential/incremental backups.
    The second retention policy type is time period based and allows you to have retention periods from 0 days to forever.
    Depending on your constraints and policies, you can configure different retention values for cloud and local storage. This enables implementation of unique backup policies, such as keeping last 10 days of backups on the local storage and last 60 days of backups on the cloud.

  10. What data format do you use for backup images?

    ZCB keeps the backup archives in well-defined and widely used ZIP64 format.

  11. For us the best time to backup MS Exchange/MS SQL Server/Windows machine is different from the best time to upload backup data to cloud. What do you recommend for our situation?

    ZCB allows different schedules for backup and for upload. For example, you can perform backups of MS Exchange/MS SQL/File server to a local disk during weekdays and schedule the uploading part to occur over the weekend. The local backup data can be either retained or deleted as per your data retention policy.

  12. Do you support backup of sparse files and hard links?

    Yes, we detect sparse files and hard links and backup only the minimal data to reduce the size of backups. At the time of restore of such files, we also restore these attributes.

  13. Does the timestamp of files change after ZCB backs them up?

    No.

    back to top
  14. Can ZCB backup open/locked files?

    Yes, ZCB can backup open files using Microsoft VSS snapshot technology. For example, you can continue sending and receiving e-mail using Outlook while backups are running.

  15. Can I use ZCB in a bare metal disaster recovery (DR) scenario?

    ZCB can help since it supports backup of Windows System State which contains important system files, registry and other operating system components. Once you have installed the operating system on a compatible hardware, you can perform disaster recovery by restoring backups of Windows System State and C:\ and other drives. You may refer to this Microsoft article for more details on the Windows System State based Disaster Recovery.

  16. How do you provide hot backup of applications such as MS Exchange and MS SQL Server?

    ZCB takes advantage of VSS-awareness of MS Exchange and MS SQL Server. When a backup starts, ZCB coordinates communication between ZCB Requestor, the Exchange and SQL Writers, and Windows Providers that create the snapshots (shadow copies) of Exchange or SQL.

  17. Can you provide hot backup of Oracle?

    Yes. ZCB supports hot backup of Oracle via VSS snapshots similarly to backup of MS Exchange and MS SQL Server.

  18. Can I run ZCB in a virtualized environment such as Amazon EC2?

    Absolutely. ZCB is fully supported in a VM environment. In fact, we utilize virtualization and Amazon EC2 resources extensively in the development and QA of our software.

Security
  1. How secure is my data with ZCB?

    ZCB provides great control and flexibility when it comes to data security. Here is an overview:



    • ZCB offers optional encryption (performed as soon as the backup data is generated) using military grade AES 256 bit encryption that uses private keys generated and managed by end user. This ensures 100% data privacy since the encryption keys are known only to the end user.
    • In addition to encrypting the backup data, ZCB provides an option to transfer your data from your computer to cloud via secure 128-bit SSL.
    • Once transferred to cloud, your data is safeguarded by Amazon S3 strict access and security policies. (Amazon S3 security document).
  2. Is ZCB HIPAA compliant?

    With proper configuration ZCB helps you maintain compliance with HIPAA regulations. When applied to cloud backup, HIPAA regulations apply in two areas - data privacy and data security.

    Data privacy: You need to configure ZCB to transfer the backup data to cloud over 128 bit SSL channel. You also need to enable encryption so that data is encrypted, even before it leaves your computer. We offer two encryption methods, both of which are secure and maintain complete privacy since the encryption keys are owned and managed completely by the end user. This means once data is encrypted, it can only be decrypted by the customer and not by any other third parties, including Zmanda and the cloud storage provider Amazon S3.

    Data security: ZCB backup data is directly uploaded to the cloud and is never sent over to any Zmanda or third party servers. Once uploaded to cloud, the cloud provider safeguards and manages the data per their security and access policies. You can refer to Amazon's security policies here: Amazon Web Services: Overview of Security Processes.

    For more information about HIPAA compliance, please see

ZCB vs. Other Online Backup Products
  1. How does ZCB compare with Mozy Professional (MozyPro)?

    Some of the key differences are:


    • Data retention: Mozy provides inflexible data retention period of 30 days only. Using Mozy you will not be able to recover your Exchange, SQL or a file going back in time for more than 30 days. With Zmanda Cloud Backup (ZCB) you control for how long you want to retain your data &mdash from 0 days to forever.
    • Live application backups: In comparison to MozyPro, ZCB supports live backup of many more applications. E.g. Mozy does not support live backup of MySQL, Oracle or SharePoint, whereas ZCB has built-in functionality for all of these applications.
    • Control and own your data: With ZCB, you own and control your data completely. The ZCB data archives stored on robust, public clouds and are in a well-known open format (ZIP64) and can be accessed by users directly. As opposed to this, Mozy stores data in proprietary format, and only way to get to your own data is through Mozy's interface.

      Also, ZCB offers geography control. Once you choose a cloud location (say Europe or Singapore), the data always stays within that geography. This may be required for regulatory compliance or for other policy reasons. You have no such control with Mozy.

    • Durable storage with well-known SLAs: Amazon S3 is a market leading cloud storage service and adheres to well-advertised and understood access and security policies.
    • Affordable: Even though Mozy Pro's prices are substantially higher, it doesn't allow you to protect multiple machines using the same license. You need to buy separate licensed for different machines. This makes ZCB far more affordable than Mozy Pro.

  2. How ZCB is different from other online/cloud backup products?

    Some key differentiators for ZCB are:


    • Comprehensive backup: ZCB can backup not only file systems (with unlimited file size, open file support, network drive support and external disk support) but also live applications such as Windows System State, MS SQL Server, MS Exchange and MS SharePoint.
    • Unparalleled flexibility: ZCB offers an unparalleled array of options so that users can use it in just the way they want:
      • Options to backup to local disk, cloud or both
      • Configurable number of threads for upload/download
      • Customized pre/post backup actions
      • Intelligent, time specific bandwidth throttling options
    • Reliable storage: ZCB leverages Amazon S3, which is robust (SLA backed), highly scalable, meets SAS70 guidelines and has detailed security policies in place.
    • Peace of mind: Coming from Zmanda, an open source company with 1,000,000+ deployments worldwide, ZCB uses open standards while storing your backup data. This enables the use of this data even outside of ZCB, providing a great flexibility and peace of mind.
Amazon S3 Cloud Environment

  1. I have purchased ZCB to backup to Amazon S3. Where is my data stored?

    Your data is stored on Amazon S3 and is owned by you (as identified by the Amazon.com account used for billing).

    However, please note that for the purpose of billing, your data within Amazon S3 is specially tagged by Amazon for use with ZCB. This means that regular Amazon S3 clients such as Amazon web console or S3Fox can't access the data on cloud directly. However if you wish to do so, you can use a modified version of jets3t, a popular open source tool.

  2. How can I check my backup data present on the cloud?

    You can use ZCB Global Dashboard, a web-application, which browses your backup data on the cloud and provides you a view of existing backup runs. This application also provides usage statistics and other useful diagnostic information to help you monitor backup activity across your ZCB installations.

  3. I host my Windows Server on Amazon EC2 cloud. What are my costs for backup?

    There is no charge for transferring data between EC2 and S3 (within the same region). You will only pay monthly license charge and cloud storage charges.

Billing and Account Management

Amazon S3

  1. Amazon S3 pricing is complex. Can you simplify it?

    We understand. But here is the best part - you don't need to worry about it! You only pay as per our pricing which is much more simple to understand. Any other charges (e.g. cost for Requests) from Amazon are absorbed by us entirely.

  2. I have multiple Windows systems to protect. How does ZCB pricing work in my environment?

    There are two options to buy ZCB licenses for protecting multiple systems:

    • Option 1: Buy only one ZCB license and use it across all systems under your control. In this case you pay $4.95 per month (independent of the number of systems being protected), plus cloud storage costs as per actual usage.

      This is an ideal option for system administrators who are putting together a backup solution for multiple Windows servers - all under their administrative umbrella, with data on all systems having identical privacy requirements (i.e. who has access to that data or not).

    • Option 2: Buy an individual certificate tied with a unique email address to protect each system. e.g. if you have three systems to protect you will buy three ZCB licenses, each associated with an independent email address - in this case you will pay $14.85 ($4.95 x 3) per month plus cloud storage costs as per actual usage. You will need to create an independent account on Zmanda Network and Amazon.com for each of these email addresses.

      With Option 2, the Amazon account for each of the email addresses associated with ZCB license will provide storage and bandwidth usage by the corresponding server. In this model there is complete privacy across systems.

  3. I'm backing up to Amazon S3. How's the billing done?

    At the end of each month, you will be billed on the basis of your actual usage by Amazon; using its widely familiar and trusted billing system. The charges by Amazon are inclusive of all the charges and you don't need to pay Zmanda any other amount separately.

    The charge by Amazon will appear in your financial statements (credit card statements) under heading "AMZN PMTS(Services and Merchandise)". The bill will have specific entries for Zmanda Cloud Backup in addition to entries for any other Amazon Web Services you may be using.

    You can also view your current and previous ZCB bills at any time by visiting the AWS Application Billing page.

  4. I want to change the credit card that I use to pay for the ZCB. How do I do that?

    As explained above, ZCB billing is handled by Amazon. To make this change, please go to the Amazon Payment Method page (requires login to your Amazon account) and edit your credit card details.

  5. I'm backing up to Amazon S3 and would like to get the invoice in a different format. Is this possible?

    The billing and invoice generation is handled by Amazon Web Services. So, if you wish to make changes, please request Amazon at devpay@amazon.com and keep zcb@zmanda.com in the CC list.

    If you just want to add some small bit of information on the invoice, such as your company name after your full name (e.g. John Doe, XYZ Systems), you can edit your Amazon account details to achieve this. To do so, please go to your personal information page and click on the "Change" button against the Full Name field.

  6. I'm backing up to Amazon S3. How do I cancel my ZCB subscription?

    There is no long term contract for ZCB. Any monthly fee paid for unused days in the month will be refunded to you on a pro-rata basis. To cancel, please go to the Cancel ZCB page (requires login to your http://network.zmanda.com account)

  7. I'm interested in backing up to Amazon S3. Is there a free trial?

    No. But since our $4.95 monthly license fee is prorated (which means you get a refund for the unused duration of the month) and we offer a 80 GB free tier to all customers, your net evaluation cost will be insignificant (less than $1 in most cases). This means you can evaluate a complete product at your own pace and put ZCB in production smoothly, when you are ready, without needing any extra steps.

  8. What do you mean by the "80 GB free tier" for Amazon S3 usage?

    As mentioned on our pricing page, we offer 10 GB free usage for each of the Amazon S3 cloud location. Since there are 8 Amazon S3 locations available for backups and since ZCB allows you to simultaneously use all of these 8 cloud locations, you can avail free usage for first 80GB of your data.
