Backing up 180TB, 15825579 files @ 185KB/s :(

We normally see good performance (what I expect from nfs, 10GB connection and 6x LTO7 drives).

 

But currently I am at 168 hours, 108,989,304 kilobytes backed up.

 

I've checked network, media server, robot, and nas storage. All are opereating normally and optimally. When I try rsyncing files off I'm seeing speed I would normally expect.

But in terms of netbackup I have no idea where to even start looking to see the issue. I mean backing up at like 185KB/s seems completely ridiculous.

 

Thoughts?

      Testing with tar, I get the speed I would expect. Even rsync across the nfs share.

       

      This is def something related to Netbackup :\

        You did the tar with the same backup selection as you choose in NetBackup?

        Makes no sense that you get different results when using Linux's tar and NetBackup's tar.

    How fast is it if you just copy some files from the NFS share to the local file system o the media server ?

    Additionally, make a small backup from the NFS share, just enough to watch it go slowly for say 10 - 15 mins - then when the backup complates, look in the Details Status of the job for the lines that look like:

    bptm waited xx times, delayed yy times
