"Item is locked by running session"

[SlothCroissant]

Hi there,

I opened a support case for this but was unfortunately automatically closed due to high support volume (which is a disappointment in itself but not what I'm here for today).

I'm getting the following error when backing up to an SMB share via Veeam Agent for Windows:

Code: Select all

6/23/2019 8:57:03 AM :: Full backup file merge failed Error: Item [svr01-backup2019-06-10T003010.vib] is locked by running session svr01-backup [Agent Backup] 

This has been failing since June 10th. There are certainly no backups being performed to that VIB - I've rebooted the Veeam Agent service as well as rebooted the machine with no change.

There are docs for what to do if Veeam Backup & Replication has this issue, but not for the Windows Agent > SMB. Can someone point me in the right direction for how to resolve this, aside from nuking the backup history and starting fresh?

Thanks!

Hello,
and welcome to the forums.

Usually I would say "ask support", but as you already mentioned, you use the free version which has only "best effort" support.

Did you already try to to run a new active full backup? If that does not work, then you could try to remove VAW and re-install it. Keep in mind that uninstall / install always requires a new full backup. You do not need to delete the old backups in any case.

Probably there is a better way to solve that, but that brings us back to point 1...

Best regards,
Hannes

I realize this is an old thread, but I had this same issue on my home PC and found the fix. Thought I'd post it here for others as this thread is one of the top hits on google.

1. Install SQL management studio
2. Stop the VeeamEndpointBackupSvc service
3. Open SQL management studio as SYSTEM and connect to (LocalDb)\VeeamEndPoint
4. Run the following query on the Veeam db (back it up first if you wish):
   

   Code: Select all

   delete from [Backup.TrackedActions.Leases]
   delete from [Backup.TrackedActions.LockItems]
   delete from [Backup.TrackedActions.Locks]

5. Start the VeeamEndpointBackupSvc

I did a more detailed write up here

Since I can't edit my post, a much quicker option is to use sqlcmd. open cmd.exe as system and paste

Code: Select all

sqlcmd -S (LocalDb)\VeeamEndPoint -d "VeeamBackup" -Q "delete from [Backup.TrackedActions.Leases]"
sqlcmd -S (LocalDb)\VeeamEndPoint -d "VeeamBackup" -Q "delete from [Backup.TrackedActions.LockItems]"
sqlcmd -S (LocalDb)\VeeamEndPoint -d "VeeamBackup" -Q "delete from [Backup.TrackedActions.Locks]"

I know this is a pretty old post but did any of you attempted stopping the session via the interface instead of applying the kb 1487(https://www.veeam.com/kb1487)? (right click stop in the running section).

Would like to know if three is a more recent resolution for this...

I'm having the same issue but can't seem to clear it with sqlcmd. My SQL skills are limited. What do I need to do to get this to work? I tried connecting with SMSS but had no idea what to use at the login screen.

"C:\WINDOWS\system32>sqlcmd -S (LocalDb)\VeeamEndPoint -d "VeeamBackup" -Q "delete from [Backup.TrackedActions.Leases]"

I have the same issue...
log shows:
Initializing
Err: Item [Job xxx] is locked by running session Job xxx [Agent Backup]
Processing finished with errors at d/m/y

running the above sqlcmd gives me the same error as above: "Server is not found or not accessible"

Follow mdxyz's detailed write up at the end of his post. It worked for me, I just needed to empty the backups folder after and start a new full backup. Did it last night

Thanks pstoric83... I went back and re-read the instructions. I didn't notice you had to use psexec to get the right permissions to use sqlcmd.
I incorrectly thought running as administrator was enough.
Also, fyi, resetting the database is easy to do, even without sqlcmd. https://www.veeam.com/kb2335. Thanks again.

Yep I did thte exact same thing lol

Look at the machine services where the error occurred. There will be 2 services. Restart veeam transport svc and veeamdeploymentSvc. The problem will be fixed.
