Ideally you should turn it off after all V3 pool files have either been
migrated to the V4 pool (because a new V4 backup matched the old pool file)
or have been deleted (because no backups refer to them).
You can tell this from the status message:
Pool is X+YGiB comprising...
X is the V4 pool
hi,
BackupPC working great with version 4.2.1, on the servers that I did an
upgrade from version 3.3.x to 4.2.1 when can the PoolV3Enabled box be
unchecked?
We only retain backups for 90 days so I should be able to turn it off
after that or do I have to leave it enabled forever?
