Virtual Machine Backups Suddenly Got Slow
Hello, In December, our backups of VMWare full virtual machines suddenly slowed way down. At that time a staff admin recreated datastores and bumped the VMFS version from 5 to 6. There were no other changes that I'm aware of. Agent based backups run fine. Only Virtual machine backups run poorly now. It doesn't matter whether I backup to disk or tape, they never achieve a rate above 300 MB/min. Ideas on where the bottleneck is? Something is limiting the communication from Backup Exec to vCenter. I have a case open with support, but they are not figuring it out. I run BE 21.4 on a physical Windows 2016 server. Backup targets are NAS appliances and direct attached SAS tape drives. The server has teamed NIC that connect to three VLAN's: data to servers, second to NAS appliances, and third to underlying SAN appliances that host our VMWare environment. Our VMWare is old: 6.5. Thanks for your help. Ray
Backup Exec 15 Restore from Disk performance issues
Hi, We are having problems with performance when restoring from disk on backup exec 15. We're running an ESXI 5.1 cluster and several servers got hit with ransomeware. We are restoring our fileserver first from a datadomain (Current software 6.0.0.9-544198) target for backup to disk and when restoring it starts at 1468 MB/Minute restore and then drops down to somwehre between 40 and 68 MB per minute. We have over a terabyte to restore in all and cannot afford the extended time to restore. We ensured that the network for restore and connection is set to 9000 MTU and rebooted but still unable to get better speed. Most searches either returns information for restores from tape or backup performance tuning. Until the ransomware, backups were working just fine with no known performance issues.
