Is it safe to delete all files from the /tmp folder of a Netbackup Appliance.

[S_R]

Hi everyone,

One of our Netbackup Appliances has too many files (total of 1261936) in the /tmp folder.
Some are over 1 GB in size. I have trouble transferring the DataCollect output file when requested to post it.

Is it safe to delete all files from the /tmp folder of a Netbackup Appliance (ver. 2.5.3).

Regards

These tend to be vmdk and telemetry files - there should not be an issue deleteing these whilst nothing is running on the appliance

So no backup jobs, no compaction or queue processing running

Probably best to take NBU down, give it a few minutes and then do it - and avoid 12 noon and midnight so you dont try it near to queue processing (though that shoukd really use a different location for caching its files)

If unsure then check with support

Are they new or old files? (wondering if they were put there pre 2.5.3)

Are they vmdk file? (wondering if you have an issue with VMware backups - crashing or multi paths to datastores)

The vast majority (number of files) are errfile,infile,outfile with size of 0 or few bytes,  but also some vmdk(some of which 1-2 GB in size), xml,cfg and others.All files are old.

I would guess most are pre your 2.5.3 upgrade then - which fixed most of these errors

You should be fine to go ahead and clear them out

multi pathing for VMware is still not supported so you may want to look at that in case that contributes towards the vmdk files
