Veeam ha annunciato il rilascio di un importante aggiornamento relativo a Veeam Backup & Replication v10. Il nuovo update non è il classico rilascio volto a risolvere piccoli problemi o sistemare qualcosina in termini di performance ma si presenta come un qualcosa di più corposo che si porta dietro tante novità interessanti, tra cui:
- Supporto a Windows 10 version 2004 e Windows Server SAC version 2004
- Supporto ad Azure Stack HCI H20 (preview)
- Supporto a Linux Kernel version 5.7 per le guest VMs
- Supporto a RHEL 8.2, CentOS 8.2, Oracle Linux 8.2 (RHCK) e VMware Photon OS per guest VMs
- Supporto a 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) e Fedora 32 (up to kernel 5.7.7)
- Supporto a VMware vCloud Director 10.1
Non mancano miglioramenti su mondo della gestione backup NAS, restore dei dati, integrazione con il cloud, parte di storage e gestione licenze.
Relativamente allo storage, arriva un’importante novità in merito all’integrazione con ReFS, perchè adesso il valore, RefsEnableLargeWorkingSetTrim, viene impostato automaticamente da Veeam quando viene riconosciuto un repository nuovo con a bordo Windows Server 2019. Per fare un po’ di storia in merito, questo parametro è sempre stato disattivato di default (in Windows Server 2016 e superiori) per evitare l’uso intensivo della memoria, dal parte di ReFS, nella gestione dei suoi metadati.
Il valore può essere cambiato manualmente via registro ma ovviamente è bene seguire le indicazioni date da Microsoft, all’interno di questa KB: https://support.microsoft.com/en-us/help/4016173/fix-heavy-memory-usage-in-refs-on-windows
Non solo miglioramenti, come detti, ma anche risoluzioni di problemi con oltre 1200 aggiustamenti, provenienti dai clienti, e bug fix di varia natura, tra cui troviamo:
- 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’s 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 contiene al suo interno anche le relative Cumulative Update 1 e 2.
