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
BE Slow SystemState Backup
Was wondering if anyone has seen this issue or has a fix We have been noticing that for some of our customers that the backup jobs been taking longer than they used to and it seems to come down to the SystemState portion of the backup. It seems to have almost doubled / two and half times increase in the amount of time it takes vs before. (where it used to be about 45 min now closer to 2hrs) This seems to be across BE verions (20.3 and 20.5) and Server verions (2016, 2019) and it just seems for 1 customer it seems to have been the latest November Windows Updates, but have been seeing this before with different customers as well prior to the november updates Been doing tests as well in my test enviroment to try to find a cause / common reason but cant seem to find one
Slow backup to tape
Hi, We're having some trouble backing up virtual and physical servers to tape. We're not getting the speed it should get and it takes up a lot of time to back up the environment. 2,63TB of data takes up more than 24 hours. Information about job, tape & tape drive: Tape type:HPE LTO Ultrium 6 6,25TB MP RW Tape Drive: MSL 2024 Compression: Hardware Encryption: None Verify: Yes These backups are going through the internal network within the domain. The average backup speed is 4,300MB/m (which is way to slow) When we backup locally on the backup server (for example the D:\ drive where the incremental disk backups are saved on the backup server) it gets to a speed of 10500MB/m. Which is understandable considering it's a straight connection to the tape drive. What did we do to try and resolve it: * Checked the compression * Checked encryption * Replaced tapes for new tapes * Resetted the tape drive * Updated Tapedrive firmware * Checked out the network for inconsistencies (not found), file transfers via other apps around 126mbs from server to server) * Job from VM on hyper-visor to tape (around 2,900 MB/m) * Local disk to tape (between 10500MB/M and 13500MB/M) * VM to disk on the backup server (Around 6200MB/M) Help would be appreciated.
