Hello,
I'm facing a strange behavior, that may be normal or not, but I don't know how to show
IHAC who had to create a On-demand Backup in NMC before a maintenance Window.
The protection policy used is DR Mirror then Backup.
The usual schedule:
Primary node: some hourly and daily snaphots
retention in the policy are :
hourly: 1 day
daily: 1 week
weekly: 2 weeks (usually never used since there is no weekly backup scheduled)
Secondary Node: 1 mirror per day
Tertiary node: some daily and weekly backups
retention in the policy are :
hourly: 1 day (never used)
daily: 1 week
weekly: 30 weeks
The customer decided to create an on-demand backup with retention weekly since it should replace the scheduled remote weekly backup.
After now nearly one month, the weekly on-demand backup is still on the tertiary node, which is OK but it's still on the primary node as well despite a policy retention of 2 weeks.
I wonder if this is normal or not:
I thought about 2 reasons why the weekly backup on the primary node would not be deleted:
- The retention applied is the one of the remote node instead the one of the primary node. Why would that be ?
- The weekly snapshots are only deleted when new weekly snapshots are created and in normal use, no weekly snapshots are scheduled by this customer.
Before opening a case, I would like to know if this is an expected behaviour and why.
Thank you
Regis
