Re: [Duplicity-talk] backups larger than source

[Matt Chipman]

Thanks Edgar,

Backuppc does deduping via hard links and I think Duplicity is storing multiple copies of the same files (via hard links) instead of just the hard links and the original file.

I think I will have to rethink how I prepare my source as its ~800GB deduped

does my reasoning make sense?

TIA

cheers

duplicity should not follow symlinks but treat them as files.

you can run your backup in max verbose mode '-v9' and observe which files get backed up.
