Veeam Backup & Replication v10a

Veeam has been announced the availability of new big update for Veeam Backup & Replication v10. The new update, is not the classic release to fix issue but introduce a lot of new enhancements in each area:

  • Support to Windows 10 version 2004 and Windows Server SAC version 2004
  • Support to Azure Stack HCI H20 (preview)
  • Support to Linux Kernel version 5.7 support for guest VMs
  • Support to RHEL 8.2, CentOS 8.2, Oracle Linux 8.2 (RHCK) and VMware Photon OS support for guest
  • Support to RHEL 8.2, CentOS 8.2, Oracle Linux 8.2 (RHCK), Ubuntu 20.04, Debian 10.4, openSUSE Leap 15.2, Oracle Linux 8 (up to UEK R6) and Fedora 32 (up to kernel 5.7.7) 
  • Support to VMware vCloud Director 10.1

Enhancements also about NAS backup, restore, cloud integration, storage integration and licensing management.

On Storage Integration, I just want mention the ReFS integration because, based on the recommendation from Microsoft, RefsEnableLargeWorkingSetTrim registry value is now automatically set upon the creation of a Windows Server 2019 based backup repository. This settings was disabled by default in Windows Server 2016 and above, to avoid heavy memory usage when ReFS try to update and manage metadata.

The settings can be changed manually via registry so for more details, check this KB from Microsoft: https://support.microsoft.com/en-us/help/4016173/fix-heavy-memory-usage-in-refs-on-windows

Not only enhancements, as I said, but also fixes with over 1200 minor enhancements and fixes based on customers feedback, like:

  • Object storage: increased performance of downloading backups from the Capacity Tier by 50%; increased restore performance from Microsoft Azure Blob Storage directly to Azure VMs in a few times; a number of under-the-hood enhancements for improved reliability.
  • NAS backup: multiple bugs were fixed around corner cases based on support cases from early adopters. Please note that the first run of file backup and backup copy jobs after upgrading to 10a may take longer due to the metadata health check, to ensure your NAS backups do not suffer from the addressed issues.
  • SQL Server transaction log backups: fixed a bug in log retention logic for Always On database log backup that may result in data loss due to deleting an incorrect log backup; improved SQL log backup metadata generation performance.
  • Application plug-ins: large number of core engine improvements to increase plug-in jobs performance and scalability and reduce configuration database load; removed conflicts between storage snapshot only jobs and plug-in jobs.
  • Instant recovery: instant restore of Veeam Agent for Linux backups will now set original CPU and RAM settings for the provisioned VM.
  • File level recovery: reliability improvements in a number of corner cases; mount servers with the File Server Resource Manager role enabled should no longer leave image files behind in their file system.
  • Backup copy jobs in the immediate mode: added support for replication from backups created from backup copy jobs; removed re-transfers of already copied backups for backup chains with transform to rollback option enabled.
  • Tape: backup to tape jobs should no longer skip processing agent-based backups created by backup copy jobs in the immediate copy mode and transformed synthetic full backups; email report should again show used tapes; file to tape jobs should no longer fail to enumerate large NFS v3 shares
  • Scale-out backup repository: improved evacuate performance; removed periodic extent status scans when there‚Äôs no active tasks requiring the given extent, not to prevent storage devices from going into sleep.
  • Resource scheduler: added backup infrastructure resource status caching and optimized configuration database queries to accelerate resource assignment and reduce configuration database load.
  • UI: multiple fixes and enhancements to improve UI responsiveness, reduce resource usage and configuration database load on SQL Server; multiple improvements in Veeam Agent for Unix integration.

Veeam Backup & Replication v10a contains also Cumulative Update 1 and 2.
