2.0.3.9 Backups are still slow?


#1

Hi guys, I don’t know… all my backups seem slow since all versions after 2.0.3.5. I’m under the impression check-filetime-only is not working.

I am making a local disk to disk backup now. 100 Gigs, 100k files, no changes since last backup - which took 2 minutes. Now with 2.0.3.9, it is taking long… will see how long. 20 minutes?

Again I have to revert to 2.0.3.5 :frowning:

Also it says weird things like “1 Dateien (-10190233 bytes) to go”. Also I have seen “1 file (0 bytes) to go”.

EDIT: While it is running I can see, Sysinternals Process Explorer reports I/O of ~70 MByte Read (per second I guess) permanently on the Duplicati Process. So I think it reads whole files. Now that will take long.

Best regards

Thanks for the info.

The negative “bytes to go” issue with 2.0.3.9 is known, but not yet fixed.

As for the performance, I hadn’t heard anybody yet report that it’s apparently reading entire files even with --check-filetime-only enabled. I know there’s a “metadata not changed” issue floating around as well that might be related.

Hopefully we’ll find those are indeed related and can be resolved with a single fix.
