Hello Iosif,
Just to be sure, what do you mean by "Can you check sizes in parallel"?
I have already looked at the two backups, from v3 and v4, and compared them.
There are NO differences in the exports. Same size, same content, everything identical.
If I start with a smaller list of files for the backup, I still see a difference. However, the difference becomes smaller.
If I start with a smaller list of files for the backup, I still see a difference. However, the difference becomes smaller.
Regarding my setup: BackupPC v3 and v4 are installed on different servers.
Greetings
Stefan

That's interesting. Can you check sizes in parallel?
Going from top to bottom, comparing the biggest directories first,
entering the one that shows the biggest size diff, etc.?
If there is a big difference, I do not really understand how you cannot
find at least one particular file or dir co-responsible for that
difference.
It takes some time, of course, but since this happens only on some of your
hosts, I suspect you can solve the mistery only by hunting this down on
these affected hosts.

What if you start back-ups repeatedly from scratch (and at the same
time...), but increasing steadily the dirs you do backup?
I'd probably start only with /home, excluding /tmp, /mnt/, /var/, ...
Would you still see size differences...?
Btw: what's your set-up, do you have different servers for BacupPC v3 and
Backup PC v4?
Thanks,
Iosif Fettich
