Version: v2.2.1

Hotfix Build 4088
Released: 3/22/12

This hotfix addresses an issue where failures in a backup job can cause the latest successful backup to be impacted. All users are recommended to update to this hotfix build.

Build 4043
Released: 3/7/2012

Upgrade Notes

While this release in a minor release containing small improvements and fixes, users upgrading from versions prior to v2.2 should note that they will encounter significant changes in Alike. Please read and understand these changes before upgrading. Two features have been removed or replaced in v2.2, so please be advised. "Standard" or "XVA" backup jobs are no longer offered in Alike. All existing XVA backups are automatically migrated to Enhanced Backups, which offer superior performance and reliability. Additionally, Optimize jobs have been removed and are also no longer offered as a job extension. Alike now continuously performs in-line defragmentation, eliminating the need to run Optimize jobs.

Due to significant changes to Alike Free, these users are highly advised to read through all the changes below prior to performing the upgrade.

Important Changes Introduced in v2.2

  • Support for XVA-based backup no longer available. Users with XVA backup jobs are automatically migrated to Enhanced Backup jobs.
  • Introducing VM Validate feature for Alike Standard and DR. The VM Validate feature automatically checks backup data consistency in the background, and places a check mark next to the version when validation is successful. Users may manually validate a VM in the VM Explorer view at any time.

Important Changes to Alike Free Edition

  • Alike Free users have been granted use of a single ABD (limited to 1 IP) in order to replace XVA based backup jobs. Free users will need to complete the ABD deployment portion of the configuration wizard during the upgrade process.
  • Although Alike no longer supports XVA based backup jobs, prior xva based backups will still restore properly.
  • Alike Free users can now perform "Enhanced Backup" jobs.
  • Alike Free users have been granted use of the "restore to XVA" capabiliy.
  • Alike Free users will not have access to File Level Recovery or VM Validation features.
  • Alike Free users' vm retention limits have been reduced to 1 per VM.

Improvements in 2.2.1

  • By default, Alike will now prevent VM validation from running until all active backups are complete. This can increase performance for users with slower ADS equipemnt.
  • Backup commit times have been improved by tuning file search and move operations.
  • Load to the ADS generated by the BackupScheduler service has been throttled, and can be tuned if needed by QuorumSoft support.
  • QuorumSoft support can now tune an Alike installation to disable XenMotion for ABDs and start them local to the target host instead.
  • Data purge times have been decreased by limiting number of I/O operations required.
  • Alike will now archive its databases after VM validation has completed, not after backups complete, to improve transaction integrity when archiving the ADS.

Bug Fixes in 2.2.1

  • Fixes issue where users upgrading from earlier versions of Alike could experience service crashes on startup.
  • Addresses data retention issue introduced in 2.2.0 specific to single-pass backup and replicate.
  • Fixes issue introduced in 2.2.0 where the Alike UI would not list all SRs.
  • Fixes problems encountered during I/O error recovery of network intermittancy.
  • Fixes issue introduced in 2.2.0 where the VM validation queue could stall backup jobs from completing.
  • Addresses issue where the Alike 2.2.0 UI could not enumerate VMs on some hosts.
  • 2.2.0 introduced a bug where backups that had not been validated were not purged, causing recent backups to be purged instead.
  • Longstanding bug where Backups with impossible dates, especially initial backups, has been fixed.
  • Addresses pre-existing bug where manually purging the latest version of a VM backup could impact future backups.
  • Fixes issue in vaulting introduced in 2.2.0 where BackupScheduler would crash when databases grew above a certain size.

Version: v2.2.0 build 4039
Released: 2/21/2012

Upgrade Notes

This release is a major release, and contains significant changes. Please read and understand these changes before upgrading. Two features have been removed or replaced in v2.2, so please be advised. "Standard" or "XVA" backup jobs are no longer offered in Alike. All existing XVA backups are automatically migrated to Enhanced Backups, which offer superior performance and reliability. Additionally, Optimize jobs have been removed and are also no longer offered as a job extension. Alike now continuously performs in-line defragmentation, eliminating the need to run Optimize jobs.

Due to significant changes to Alike Free, these users are highly advised to read through all the changes below prior to performing the upgrade.

Overall Changes

  • Introducing VM Validate feature for Alike Standard and DR. The VM Validate feature automatically checks backup data consistency in the background, and places a check mark next to the version when validation is successful. Users may manually validate a VM in the VM Explorer view at any time.
  • A new install wizard now guides users through initial configuration of Alike. This wizard helps assure all important settings have been selected and tested and that users get the most out of their Alike installation.
  • The ability to restore directly to XVA files now available for all backups.
  • Support for XVA-based backup no longer available. Users with XVA backup jobs are automatically migrated to Enhanced Backup jobs.
  • The Alike Data Store (ADS) requirements and load on system resources has been greatly reduced, using less overall memory in Windows 2008R2 and similar environments.
  • Alike is more efficient at both finding unused data to purge, and reclaiming it.
  • Default installation block size has been increased from 256KB to 512KB. This change may result in increased performance and reduced database sizes. The new blocksize is only set on new installs, upgraded users will remain at the old size.
  • Users may now perform multiple restore jobs simultaneously
  • Alike's automatically scheduled System Consistency Check has been removed, as they are supersceded by the in-line maintenance.
  • Improvements to Enhanced Replication offer better handling of network failures and intermittancies.
  • Offsite Vaulting received numerous bug fixes. Offsite vaulting performance has been improved
  • Various improvements to UI responsiveness.

Changes to Alike Free Edition

  • Alike Free users have been granted use of a single ABD (limited to 1 IP) in order to replace XVA based backup jobs. Free users will need to complete the ABD deployment portion of the configuration wizard during the upgrade process.

  • Alike Free users can now perform "Enhanced Backup" jobs.
  • Alike Free users have been granted use of the "restore to XVA" capabiliy.
  • Alike Free users will not have access to File Level Recovery or VM Validation features.
  • Alike Free users' vm retention limits have been reduced to 1 per VM.

Known Issues

  • To-filesystem XVA restore does not properly handle all Linux VMs. While disk data is valid for these XVAs, improper metadata prevents the VMs from booting.
  • File-level restore may not be able to expose ext3 and ext4 filesytems. These filesystems can still be fully recovered using Enhanced Restore.

Released: 9/16/2011

About this release
This version is a major release. Existing customers are urged to read and understand product changes before upgrading.

Upgrade Notes

  • Alike must analyze your existing Data Store and convert it to the new ADS format during the upgrade process. This process can take a very long time for large amounts of data, please plan your upgrade accordingly!
  • After the upgrade completes, you will need to log into XenCenter and delete your existing ABDs from your XenServer hosts and deploy the new ABD image from the UI.
  • Alike relies heavily on CIFS for Enhanced backup and Replicate operations. If you are using a local data store, Alike will attempt to create a Windows CIFS share for you. You must have Windows Sharing enabled
  • Please be aware that the faster your CIFS Data Store performance, the faster Alike can operate. If you have a high-performance CIFS NAS, consider moving your Data Store to it

  • Offsite Vaulting incorporates improved handling of large VMs
  • UI improvements to screen loading and responsiveness. Activity page and Job Log Details have been optimized
