Catalog build failure DPM 2016

[Vicky]

Hi guys,

 

Been having a lot of issues with our DPM server. Basically i had Microsoft support remote on to take a look at a separate issue. The tech emptied the temp folder which removed the MTA folder. I had no idea this folder was in there until i got back into work from the weekend to see all the tape backups had failed. After a quick Google search i found out this MTA folder is needed during tape backups so re created it and the tape backups ran. Now im getting the following warning.

 

The backup tape job completed, but the catalog was not built correctly for although no data was lost, you must rebuild the catalog to access the data of the backup job (ID 3312)

 

file copy failed due to an I/O error.

Source location:\\\MTATempStore$\file.mbc

Destination location: C:\program files\microsoft system center 2012 r2\DPM\DPM\Temp\file.mbc

The network name cannot be found.

 

Ive looked at the active shares on the server and it turns out the MTATempStore$ share is missing.

 

Does anyone know how i recreate this share and what permissions i need to use, or if this is even the issue, anyone seen this before?

Basically an MTA folder within your normal temp path e.g.

 [DPM_INSTALL_LOCATION]\Temp\MTA

 

So in your example:

 

C:\program files\microsoft system center 2012 r2\DPM\DPM\Temp\MTA\

was the share path unless it's changed recently, permissions wise I couldn't tell you off hand without looking at another system

 

Before you do any manual changes though, have you rebooted? As it used to re-create it on reboot if it couldn't find it on the older versions

Ok, thanks, ive re created the share and set the permissions i think it needs, have to see what happens. I did try a restart but it didnt bring the share back.

 

Ive tried re running the job in DPM, but it just sits there it doesnt even try to re build the catalog, so im not sure if re creating the share has worked yet :/
