Now that the filesystem is working should I take a partclone backup or
a dd backup ?
Partclone is small but since as you say the filesystem is not
completely fixed, my backup may be messed up.
While a dd backup keeps things the way they are.

I too believe that the repair is not complete. I say this because when
I started my system my swap file could not be activated and System
Logging Service failed to start.
I have disabled my swap file and will recreate it and the System
Logging Service is now working after a reboot.
