[Duplicity-talk] Using `remove-older-than` correctly

[howard chen]

Hello,

I have a folder that need to backup

1. I want to alway have a full backup of that folder, no matter the
files have been untouched for a year or more
2. I want to keep 30 day of history to rollback, e.g. I can alway
rollback to the backup of last week

Currently I am using


duplicity --sign-key '123' --encrypt-key 'ABC' /backup s3+http://xxxx
duplicity remove-older-than 30D s3+http://xxx


And today I found out the `remove-older-than` will remove all the
files if they keep unchanged for more than 30days, but not the 30 days
history I mentioned in (2).

So what command(s) I should be used?

Thanks.
