How do I delete old signatures?
Previously I received the error in this thread’s title, plus,
‘Fatal error: unable to start incremental backup. Old signatures not found and incremental specified Traceback…’
So I deleted the encrypted directory and secret_key.txt. This got rid of the Fatal error.
But now I just just get the ‘backup warning, found signatures but no corresponding backup files’.
Checking the encrypted directory there appears to be a duplicity-full manifest, 4 volumes, and a sigtar.gpg file.
Presumably the backup was okay and a just need to get ride of the old signatures? If so, how? Where are they?
Solved (so far anyway)
Warnings disappeared after the first warning. MIAB has completed 4 incremental backs without error/warning since the first warning. So I dunno. Seems like the issue with signatures can be fixed by doing the following:
- Turn off backups in the admin panel
- Delete existing backups (ie entire encrypted directory contents) and secret_key:
ssh into your box and run the following commands
rm -rf /home/user-data/backup/secret_key.txt
- Turn backups on again in the admin panel
- Wait a few days and any warnings should disappear
Do above I got one warning after the first backup (or perhaps first incremental backup) and then no warnings after that.
Good idea to backup your existing backups/secret_key before deleting anything.
If you remove the backup files from encrypted (/home/user-data/backup/encrypted) you should also clear out the cache folder (/home/user-data/backup/cache) as this is where the signature errors originate from.
