[Duplicati 2.0.4.5\_beta much slower than 2.0.3.3\_beta](https://forum.duplicati.com/t/duplicati-2-0-4-5-beta-much-slower-than-2-0-3-3-beta/5536/20) comments on performance. If the claim of 10x performance boost is accurate (YMMV) then possibly it will more than make up for your 8-times loss.
I don’t know if your fans will run any slower. There are [ways](https://forum.duplicati.com/t/hdd-access-speed-during-backup/5775/9) to get that, but performance will suffer…
I suspect the GUI for the Exclude section (below the Filter section) is presented by the following code:
>
and the fileAttributes name probably refers to [FileAttributes Enum](https://docs.microsoft.com/en-us/dotnet/api/system.io.filesysteminfo.attributes?view=netframework-4.8) which is the OS-supported attributes, where definitions aren’t given except for Hidden, which it says macOS has. Windows also has System:
```plaintext
/A Displays files with specified attributes.
attributes D Directories R Read-only files
H Hidden files A Files ready for archiving
S System files I Not content indexed files
L Reparse Points O Offline files
```
Above is output from `dir /?` in a Command Prompt. Possibly you know what attributes macOS can do. Bottom line is that looking at file attributes is probably fast, up to the OS, and maybe poorly documented.
[General concept of filters](https://duplicati.readthedocs.io/en/latest/appendix-d-filters/#general-concept-of-filters)
> Duplicati 2.0 can include or exclude files and folders from your backup based on so-called filters. A filter can consist of various rules. And a rule decides if a file is to be included to the backup or excluded from it. This decision is made based on the name of the file or folder. Besides these name-based rules there is also a set of specific settings which exclude files with specific attributes (like system files or hidden files) or files that exceed a specific size.
Choice between ways can be nice – _or_ confusing. If somehow the speedup in Filters isn’t enough, you could try the attributes Exclude instead, but I have an (unproven) suspicion that it won’t be as effective.
