I am currently using a duplicity script to backup my 110G/2T CentOS server to a 2T sftp server.
Since 4 days passed, duplicity backed up just 90G. This is not a problem. The main problem is; I have got nearly 600G cache that duplicity generated at "/user/.cache/duplicity". This size is not normal, so what should I do? Will duplicity shrink or remove these cache files and folders when finished the task? Will duplicity backup it's cache too (I did not exclude the /user folder)?
Additional info: I am using Hetzner server and this is the backup script that I am using: https://wiki.hetzner.de/index.php/Duplicity_Script/en
In addition, I just excluded directories proc, sys and dev from the root (and backed up everything else starting from the root, because I wanted a full server backup).
