You might try running CHKDSK on that F: drive to see it it has any problems.
Also try running REMOVE_UNKNOWN.BAT. in the urbackup directory to clean things up.
I think that is what it is called on Windows Servers.


#3

Thanks for the answer
But couldn’t find any “REMOVE_UNKNOWN.BAT” , the only *.bat i fond is as follows
enable_debug_logging.bat
enable_internet_only.bat
prefilebackup.bat

any idea?
Thanks


#4

Can you have a look into the windows system/application event log?


#5

Manual says it is here on the Windows urbackup Server:
C:\Program Files\UrBackup\remove_unknown.bat


#6

OK I run the command

urbackupsrv remove-unknown

my server runs under jails on Freenas , when i run it i get following errors , any idea what about the SQLite errors?
Thanks

Ah, you have a urbackup Linux server, not Windows.
Looks like you have a database problem.

Try this on the urbackup server–> urbackupsrv repair-database

If that doesn’t fix the database, you may need to reinstall the server software.

You might also check permissions and ownership on the directory and all files in /use/local/var/urbackup

I am out of ideas after that, maybe someone else has other suggestions.

you where right it where permission issue , but now i have new issue

Looks like a database problem.
If the urbackupsrv repair-database doesn’t fix it, you may have to remove/reinstall.
I’m in a similar situation, waiting to here from the experts before removing server and reinstalling it.


#10

I did “urbackupsrv repair-database” , didn’t fix it ,are you suggesting to wait little bit more or reinstall it
any way what you suggest as procedure to reinstall coexist with current data backedup?
Thanks again


#11

I just thought of something,
If you have yours set up to backup the databases, you could try copying the backup database files back to original location.
I think you would have to shutdown the server software first, then restore the files.
My backups have missing files, so I don’t think I can do that.
Check your /var/log/urbackup.log file to see if you have any additional errors.

Reinstalling would most likely destroy the database. If it is corrupt, not a loss anyway.
I don’t know if the software is capable of rebuilding the database from existing backups or not.
I have stopped all my backups and am waiting for advice as I am not a database person.


#12

i don’t think i did database backup , unless its set automatically by Urbackup ,in such case where its should be expected to be found?


#13

Third line from bottom,
Backup files would be in /<Your_Backup_Folder>/urbackup


#14

ok, Thanks, i restored from backup its works, but now I have new errors on the client side as follows below,
Are those errors could indicate issues with that volume (chkdsk needed)?
thanks

I have had same issue on two new small servers recently. The server motherboards were Intel and I used the on board RSTe driver for the RAID. I couldn’t get anywhere. Gave up and re-installed the system but used the on board ERST2 driver instead, then all works without any failures. I realise you cannot do this on a production server but worthwhile thinking about the drivers for new machines.
