NextCloudPi version v1.17.1
NextCloudPi image NextCloudPi_07-21-19
distribution Raspbian GNU/Linux 9
Nextcloud version 16.0.5.1
runs on a Raspberry Pi 4 (4GB)
there are two USB Sticks connected to the raspberry Pi.
-first one as Data directory
-second for Backups
when i do a backup with “Include data” = deactivated everything is fine and i can find the *.tar file on the second USB-Stick. But with “Include data” = enabled it fails with Input/output error. No matter whether it’s a manual or automatic Backup

i have formatted the “Backup”-stick again.
Now there’s no more I/O error. The function takes longer now, but there is still an error.
Also i can find the backup-file on the USB-Stick, wich is as big as i would expect it (~20GB). I suppose the error appears at the very end of the backup.
