Flashbackup-Windows socket read failure Err 13

Hi,

Having managed to get the Flashbackup-Windows policy to validate (problem with the firewall) now I am getting an Error 13 each time the backup runs.

The snapshot part of the policy completes without error and the backup start Ok but gets to about 400128Kb and 325500 Files and terminates with the following in the activity monitor:

The data area is approx 3Tb in size and is comprised of millions of small files, this is sat on a 10Tb disk so I know that the snap space is adequate >15% could this soley be down to IO issues whist backing up the snap from the same disk, also is there any rules that need to be followed when using an alternative host for the backup IO?
 
The backup is curently being performed onto a B6200 using OST

  • Looks like we fixed this problem ourselves... we found that the application was creating recursive directories for whatever reason and one of these was also causing Storage Essentials to fail on a discovery, we did scan the area and this came back Ok so we deleted it and re ran the SE which worked (we still have a few other recursive directories but these seem Ok) so I re-ran the Flashbackup policy and this is now working Ok.

    Not sure what was wrong with the directory but that was definately the issue.
