Back In Time

Reducing size of snapshots

Asked by Maksym Walczak

Hello,
What I realized is that whenever a change in files I'm tracking is detected, all the files are being copied to backup storage instead of only the files that were changed. Is there some way to backup changes only instead of mirroring all files every time?

As long as the filesystem on your destination drive supports hard-links, BIT will only save changes. Unchanged files will be hard linked. Please take a look at FAQ #2584 and FAQ #2403 for further information on this

I see, it seems that the actual size of the files is only about 600 mb instead of 5 GB that linux shows. I checked it with du. What is going to happen when linux thinks that the disk is full but in fact it will be far from being full? Will Back in Time start deleting files?

With 'linux' you mean your filebrowser (e.g. Nautilus)? It calculates wrong. Don't get confused by that.

BIT will (if configured in remove section) only remove the oldest snapshot if your drive _really_ has less space or less free inodes than configured.

Thank you! It solved my problem and yes I meant my file browser - Thunar in this case.
