[Duplicity-talk] reduce size of cache

[Hamish Moffatt]

I have full and incremental backups of a large amount of data going back 
4 years, for which the duplicity cache is consuming 139Gb(!) on one 
machine alone.

Is there a current and supported way to remove old signatures from the 
cache such that they can be restored in the future if required? I don't 
mind how manual this process is.

I realize this has been asked in the past and the previous reluctant 
recommendation was to use cleanup --extra-clean, but that option was 
removed in 2020.


If so, what is the process for removing the old signatures, and what is 
the process for getting them back from remote if required?



thanks
