Re: cross-platform backup tool incremental rdiff-backup takes long

[Jonas Schöpf]

Hi all!

I am using rdiff-backup without flaws since this conversation here last 
year. Although I always need to add the "--no-fsync" argument in order 
to get fast (20-30min) backups.

Unfortunately, I have a problem with the current backup.
I deleted a lot of stuff on my machine (around 200GB) and if I do a new 
backup I have to abort it after 9 hours as it does not finish.

iostat -x -m 3 shows that %util is always between 70 and 95.
So I assume that IO is again a bottleneck, but shouldn't it be easy for 
rdiff-backup to just delete the files from the backup?
Is there a way how I can speed up this process?

Thank you very much and cheers,
Jonas
