Backup error

Hello,
i've got a problem with backup, some days ago they stopped working, it seemes that database backups are working correctly, but file backup faisl.
Errors are like this:

Code:

unlink(/var/backup/web11/web11_2019-05-03_09-41.zip): Input/output error in /usr/local/ispconfig/server/lib/classes/cron.d/500-backup.inc.php on line 158

The backup is a mount point in /var/backup, in ispconfig is server config there is the flag about the mount point.
Any idea?

 

p.s.: i get also this errors

Code:

gzip: write error: Input/output error
sh: /var/backup/web19/db_c0_XXX_2019-05-03_09-56.sql.gz: Errore di input/output

 

Does the mount work? Check you can write to the backup directory.
Is disk full? Check with

Code:

df -hT

Is there anything in /var/log/syslog?

 

Hello,
yes the mount seems to work, as root i can write and delete file regularly. Disk is not full

Code:

Is the size of backup directory real? That shows 256 Terabytes for /var/backup.

 

LOL!!! Yes mate, is real

 

I've done a reboot of the server and changed the s3fuse, using the one provided by distribution.
Now the result is

Code:

PHP Warning:  chmod(): Input/output error in /usr/local/ispconfig/server/lib/classes/cron.d/500-backup.inc.php on line 74

Now on some websistes backup worked, and on others failed...
