We are running a Veeam backup of one of our most important VMware guests. This VM Guest must stay on-line 24/7 and therefore we do not have a designated backup window, we must do it on the "fly".
The VM Guest has Sysbase SQL Anywhere 11 installed with a 17+GB database. The VM Guest is backed up using Veeam with "Enable application-aware image processing" set as true.
The problem we have is that when the VM Guest is being snapshot or the snapshot is being released we will lose pings to the server (network connection drops for a second or so a few times), which then causes the ODBC connection from the client's PC to the database to error.
I have contacted VMware and they have responded by saying that this is a known problem for VM Guests that have heave I/O loads.VMWare KB
Their solutions were not helpful... System downtime during backup windows is not an option and we need to find a solution.
Should I be using "application-aware" image processing (VSS) in Veeam? As far as I understand this is a must
to get consistent backups (e.g. OS files that are not corrupted).
I have had a browse through the Veeam Task logs and noticed a line VSSControl: Frozen in 12sec
, could this be causing a problem?
I would be grateful of any help on this issue or information from people who have also experienced this type of problem with VMWare and how it was worked around.
