It seems the target of the backup is not accessible. Did you try to restart the service that mounts the USB disk?
systemctl restart rclone-webdav.service
Let’s check the status:
systemctl status rclone-webdav.service -l
Are you rotating the disks between home and company? I think if the disk has changed you need to resetup the local volume.
Did you already check for hardware errors? (smart)
Maybe the disk has some bad blocks? (adapt sda to the USB disk)
badblocks -v /dev/sda -s
Please check if the USB harddisk is setup correctly as explained in Backup and restore — NS8 documentation :
To show the disks information including UUIDs:
lsblk -f
Let’s list the volumes to check if a custom volume like volume00
was created:
podman volume ls
Check if the custom volume is there:
grep BACKUP_VOLUME /var/lib/nethserver/node/state/rclone-webdav.env
Inspect the custom volume to check the mountpoint:
podman volume inspect volume00
