Instead of supporting unlimited number of days, would it make sense to implement an expiration logic a bit similar to backup applications?
For example (from rsync-time-backup)
Backup sets are automatically deleted following a simple expiration strategy defined with the --strategy flag. This strategy is a series of time intervals with each item being defined as x:y, which means "after x days, keep one backup every y days". The default strategy is 1:1 30:7 365:30, which means:
- After 1 day, keep one backup every 1 day (1:1).
- After 30 days, keep one backup every 7 days (30:7).
- After 365 days, keep one backup every 30 days (365:30).
Before the first interval (i.e. by default within the first 24h) it is implied that all backup sets are kept. Additionally, if the backup destination directory is full, the oldest backups are deleted until enough space is available.
Would there be any interest in that kind of feature?
