"zmbkpose -d" Do not exclude old full backups. #31

Closed rodrigodelmonte closed 11 years ago

In a cron job I configure to zmbkpose exclude backups older than 15 days. But I noticed that just the incremental backups were excluded and the full backups still there. This behaviour is normal?

Hi. I don't understand the question mainly because the word "exclude". The -d option remove old backups cycles trying to avoid a disk full. A backup cycle is a full backup and subsequent incrementals. The entire cycle must be earlier than the date "now - argumentto-d" to be removed. Then if you have : Day | Backup 1 FULL 2 INC 3 INC 4 INC 5 FULL 6 INC 7 FULL 8 FULL Then you on day 9 execute zmbkpose with : -d 2d => backups of days 1,2,3,4,5,6 will be eliminated. because they are earlier to day 7 (9 - 2 = 7) -d 4d => backups of days 1,2,3,4 will be eliminated. because they are earlier to day 5 (9 - 4 = 5) -d 5d => no file will be deleted because it would break the cycle between days 1 to 4 If zmbkpose not work this way, then it is a bug. Try to test using "-s" argument for simulation, and not erase.
