Déjà Dup

Is it possible to improve the compression?

Asked by Dahaniel

Till now I was using Areca for my backups but I like Deja Dup because it integrates much better into the desktop. However, my documents folder is around 6gb and the backup areca produced was around 4GB big, with DejaDup the same folder gets backed up to around 5GB, is there a way to improve the compression?

Yes and no. No user-visible way. Deja Dup works by using duplicity, which works by making a bunch of tiny tarballs. The fact that it separates the tarballs means you have less compression than if you had one giant tarball.

The size of the tarballs is something Deja Dup can change. But not the user. I have vague intentions of increasing the size, but haven't done that yet.

Thanks for the answer!

I recognized that tarballs are 30MB when making ftp backups but only 10MB for backups via samba. I sthere any good reason for that? I think samba backups will most probably be done in local networks, so something like 50 or even 100MB should be fine here.

Can you help with this problem?
