Hi to everyone,
I've been having this problem for a while and decided to search for sollution.
Veeam Backup & Repliction 220.127.116.11 (64bit, Standard)
VMware vSphere 5.1 (Standard)
VM to backup: Ubuntu Samba3 file server, containing 3 virtual disks: 8 GB, 1,9 TB and 1,7 TB.
Provisioned storage: 3,61 TB
Used (not-shared) storage: 3,29 TB
So the problem is, that full backup of this VM takes about 4 days and backup speed is degrading over all backup process. Veeam statistics for this backup job is showing, that:
1st disk average read speed is at ~66 MB/s [CBT], duration: 1-2 minutes
2nd disk average read speed is at ~27 MB/s [CBT], duration: 20+ hours
3rd disk average read speed is at ~10 MB/s [CBT], duration: 50-60+ hours
Sometimes backup fails on the 3rd disk with an error like this:
Timed out waiting for all VDDK disks to close
Error: Client error: VDDK error: 1.Unknown error Unable to retrieve next block transmission command. Number of already processed blocks: .
Busy: Source 39% > Proxy 28% > Network 32% > Target 41%
Is there any way to figure this out, why backup process takes so much time, why backup speed is degrading and why sometimes it fails?
If you need any additional info, please comment.
Waiting for some help, please
