monthly retention

[Manuel Kissoyan]

Hi,

im trying to work out my backup with a monthly retention, wondering how i
could keep a backup that is 30 days old all the time...i mean....if i rsync
the daily backup today with the monthly one in 30 days the monthly will be
the monthly backup but the day of the rsync will not be 30 days old, the
only option i see is have 3 backed up files rotating every two months to at
least keep a 30 days old one....sorry for the confusion :-)

Thank you in advance!
