reduce / optimize the backup size

[VedMod]

Hi,

i am using seedvault via calyxos on my Pixel6Pro. After i switched to calyxos and had some problems with the direct upload to my selfhosted nextcloud, i have switch the process to let seedvault save the backup local to a folder on the pixel and activated an automatic upload in the nextcloud app for this folder. For just over one year this setup works great.

I just notified that in the mean time, the folder has a size ~ 26GB!
D:\Android>adb shell du -ks /storage/emulated/0/.SeedVaultAndroidBackup
27420214 /storage/emulated/0/.SeedVaultAndroidBackup

In the backup list are no apps that is a game or other big fat storage eating apps! ;)

So is there any way to reduce my backup size? Remove not more needed files?
