I have a Raspi with a 2TB hard drive. I would like to use a second Raspi that mounts the share and runs the backups. This works well so far.
At the beginning I had problems with the permissions, the backups were significantly smaller than the original hard drive. In the end, I discovered the ‘Reset Permissions’ plugin and reset the permissions and all files were restored in the backup.
I have one folder where the backup is larger than the original. I was very surprised by this, but you never stop learning.
I took a look at the original files.
ls -ls
ls: cannot access ‘Kat12’: Input/output error
ls: cannot access ‘Kat11’: Input/output error
total 0
0 drwxrwsr-x 1 root users 240 Apr 12 15:37 Kat10
? d????????? ? ? ? ? ? Cat11
? d????????? ? ? ? ? ? Cat12
0 drwxrwsr-x 1 root users 224 Apr 12 15:36 Kat13
0 drwxrwsr-x 1 root users 448 Apr 12 15:40 Cat20
0 drwxrwsr-x 1 root users 3384 Jul 21 2018 Cat22
Kat11 and Kat12 are not present in the backup, but many other folders are.
My next thought was to try to delete the original files in order to restore them from the backup. I first tried to delete the folders in the GUI, but failed. I then tried to delete the folders in the terminal, but only got the message
rm: cannot remove ‘3D/Kat20/9561.DWG’: Read-only file system
rm: cannot remove ‘3D/Kat20/9529.ttt’: Read-only file system
rm: cannot remove ‘3D/Kat10’: Read-only file system
rm: cannot remove ‘3D/Kat11’: Read-only file system
How can it be that only this one folder ‘3D’ with its subfolders is on a ‘Read-only file system’? I have looked at the smart values of the disc, they are green, as OK.
