Hello,
I am wondering if it is possible to do multilevel backup with duplicity?
(In order to avoid the long backup chains, without having to frequent full
new backups.)
If not, I suppose what would be needed would be an option to base some
incremental backups on not the latest incremental but an earlier one (or
the full backup).
What I'm contemplating is to e.g. let the first backup every month be
incremental based on the previous month's first backup. And the same for
weeks and days, with the first within each category either based on the
previous such, or the latest of any category higher, if that is later.
Together with e.g. remove-older-than 14D, this could give a chain-tree
like this (each backup based on the previous line, unless there is an
arrow):
full
monthly
monthly
monthly
monthly
^ weekly
| weekly
| weekly
| weekly
| ^ daily
| | daily
| | daily
| | daily
| | daily
| | daily
| weekly
| daily
| daily
monthly
^ daily
| daily
| daily
weekly
daily
daily

Best regards,
