Hey,

I believe the answer is (quoting from the doc about $Conf{FullKeepCnt}): "For V3 backups, the expiry settings have their original meanings." This is not repeatead for "FullKeepCntMin" but since that parameter is part of the expiry settings, I think it applies there too.

Result: Since there are V3 and V4 pools in play here, I believe the full dated March is the last full in V3 format. It will not be removed since FullKeepCntMin=1 and because of the above reasoning.

SO: I have now removed that very old backup and the V3 pool has dropped to 0, which is ok.

However, I do not understand the difference in display here. As you can see in my previous post below, the old V3 existing file count was very high (near the total file count). In V4 I do not ever see a high existing file count. Maybe in V3 the "existing" file count meant something different than in V4?

Thanks,
Marki

Hey,

Back in March we migrated from v3 to v4.

Looking at it today, backups look like shown below.

What is this full backup dated March still doing there? Why are the
following FULL backups apparently not containing much data? (they look
identical to the incrementals)

Thx,
Marki
