2015-02-20 13:47:23 avvcbimage Info <14665>: 30 snapshots are present on this VM:
|EMC Software: Avamar 6.1 - 7.1 |
|For issue #1|
If there are Snapshot files in the Virtual Machine directory and vCenter reported less then was discovered by the scan then the backup fails.When Avamar attempts to backup a Virtual Machine, it must take a snapshot. Before performing it queries vCenter for how many snapshots the Virtual Machine currently contains. Then the Datastore directory is scanned where the Virtual Machine resides.For Issue #2
VMware ESI will only permit up to 32 before the Snapshot task fails with: Create Virtual Machine Sapshot task fails with a VMware error of: "Snapshot hierarchy is too deep". As described above we need to take a new "Avamar" snapshot (bring Snapshot count to 31). And the end of the backup we need to delete this Snapshot. This delete action causes ESX to create a hidden esx Snapshot called consolidated helper (snapshot count would be 32) and could fail due to the ESX "Snapshot hierarchy is too deep" issue. For this reason the Avamar proxy code will NOT allow Snapshots of a VM that has existing 30 snapshots.
|For Issue #1 |
Snapshot files must be removed from the Virtual Machines Datastore Directory.
Before removing the files there are some checks that must be completed.
For Issue #2.
