Size of signature files 8-80x larger that the diffs

Asked by spooky on 2010-07-15

I'm backing up a bunch of large SVN repositories using duplicity. Due to the number of commits we perform incremental backups every three hours and full backups every five days. The problem is that the diff between incremental backups is between one and fifteen megabytes (which I would expect) but the new-signatures file is always around eighty to ninety megabytes.

Funnily enough this fills our online storage space quite quickly. Is there any way that I can reduce the size of the signatures?

There's no real way to reduce signature size without a corresponding
increase in backup size. Perhaps you could go to a daily incremental
backup, and a 3-hour rsync snapshot to a local drive.
