Doing a backup over my roughly 30GB, 30’000 profile (all living on a fast SSD) with filter group default excludes takes roughly 12 minutes, at least 80% of which is spent counting files (counter goes up by about 50-100 files per second.

If I kick out filter group default excludes and just a have a bunch of excluded directories otherwise, it goes down to 2-3 minutes, most of which is spent checking backend files (which I guess cannot be avoided given duplicati’s architecture).

It definitely feels like there is something seriously wrong in the filter group code.

Wow. I just removed both System Files and Temporary Files filter groups and it dropped my backup time down from 10 minutes to 2 minutes.

Looks like this is still not fixed one year later in 2.0.4.23 beta!

See my reply to your post in that other thread…

> 2.0.4.23 has only one change from 2.0.4.5 - a warning for Amazon Cloud Drive users. It’s unfortunate that it was given this version label. Looks like this may have been resolved in 2.0.4.10, according to [https://github.com/duplicati/duplicati/issues/3395](https://github.com/duplicati/duplicati/issues/3395) If you are willing to go to a Canary release, version 2.0.4.22 contains this and other fixes not included in 2.0.4.5 (or 2.0.4.23).
