error in borg after power outage

[alansenairj]

Hello guys. I am new using borg and I don't know what to do to restart my backup.

I am using Vorta to create a backup. When my backup was working I have a power outage.

Now I am getting some python errors and i don't know how to solve it. Let me describe better.

log:

❯ borg check /mnt/sdd1/backup_home

I did a reinstall:

About borg I was working. Now It not finishing a command without crash.
I read docs but I don't know how to deal with it.

I/O Error means it is an error below borg, either filesystem corrupted or bad storage media.

So run fsck on that filesystem, check the disk with smartctl -t long.

[alansenairj]

Hi! Thanks for your replay.

I did ntfs checking. No errors. And no smart error.

root@z390:/home/alan# ntfsfix /dev/sde1
Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
Checking the alternate boot sector... OK
NTFS volume version is 3.1.
NTFS partition /dev/sde1 was processed successfully.

Does it works well using same disk? I mean, use a repo for borg at same disk for mounted rclone drive?

/dev/sde1 932G 17G 916G 2% /mnt/sdd1
csi: 1.0T 988M 1.0T 1% /mnt/sdd1/rclone_csi

[ThomasWaldmann]

Check the smart attributes, esp. reallocated and pending sectors (raw value).

I think I found one error. Joplin file structure creates too big filenames. It is syncing to my Onedrive at Rclone mounted drive. I need to enter in Windows and check disk from there to fix some errors.

I will try to stop with joplin syncing for a while to test it.

[alansenairj]

I think I got it working. I will reproduce steps.

1 - Removed entire folder
2 - Checked disk at Windows
3 - Stoped Joplin syncing
4 - filtered .cache from home backup
5 - create a new repo with other name

Now it is working.

Thanxx for any help

I am not familiar with "Joplin" or what you are doing there exactly.

But great if you could fix it. :-)
