[Bug] Yet Another "NB is very slow" bug....

[gardiol]

I have a Surya (POCO X3 NFC) running official LineageOS21 (A14) with Magisk.

My backup experience with NeoBackup 8.3.6 (installed from f-droid) is somewhat bugging me:

1. Start from a fresh installation of NB in an empty backup folder on SD card (external storage)
2. Accept root popup
3. Select a few apps (Firefox, AudioBookShelf, Catima, didUpFamiglia, EasyPark, Camera (non stock), ImageToolbox, Gaugin, Jellyfin, LibreTube, Markor, Summit, SolarMan, Termux)
4. Start a full backup using NeoBackup defaults
5. Backup ends successfully after some 12 hours, total backup size is about 12gb

Restore, on the other hand, is basically immediate or at least takes only seconds even for bigger packages.

Is this normal to be expected? Is there anything i can try to improve backup experience?

i also have similar experience with Whatsapp backup. But Neobackup also freezes other apps too
I have to force reboot
This is happening on lineage Os 21

previously I was using crdroid 10.2 (A14) on thag backups worked without any problem
