[Duplicity-talk] Recovering corrupted incremental backup

[Pierre-Alexis Ciavaldini]

Hi, 

I have a situation where an extremely important file is in a corrupted 
incremental backup. My guess to what happened is that the last recorded 
incremental backup was too heavy and could not finish writing to disk because 
it was full, so the GUI says invalid hash.

I've followed the worst case manual extraction procedure for the latest full 
backup, but now I need to do the same with incremental.

The latest incremental backup, which should contain the file (if the backup 
stopped after copying this file), has 24 volumes finishing with :

duplicity-inc.20210206T080811Z.to.20210207T090128Z.vol24.difftar

It has a .manifest but no .sigtar

Should all incremental backups be extracted and added, or only the latest one ? 
Any other advice to maximize my luck ?

Thank you
