I have forced tklbam-backup to make a full backup once per day by editing /etc/tklbam/conf.
I now have 2 full backups and several incremental backups stored on S3 for this machine.
After reading this post:
I expected the older full to 'roll off' and leave only the most current.
Can you please explain the normal behavior of full backups and whether there is a way to modify this?
Making frequent fulls, as suggested in several posts to keep the 'chain' fairly short, would use a great deal of storage space this way. Plus it seems to me that the older backups no longer serve a purpose once a new full is made.
