Hello,
Some NAS use snapshots ( Netapp) for NDMP backups & that open files etc 
should not be an issue, also make sure you have adequate disk space on 
backup server for Temp directory.

Re: [Networker] NDMP indexing?






I have a similar issue I am dealing with right now.  What I was seeing was 
one of the directories on our NAS devices was backing up successfully, but 
the indexes were failing and I had no idea because the savegroup reports 
were reporting a  successful backup had "succeeded"....lesson learned to 
look and make sure all the indexes are written.

The problem we found out that is if you have any process that is writing 
to the NAS devices during your backup process, then the indexes will fail 
unless you have something like Snapsure running.  We do not use Snapsure 
(yet), so we are always looking that the data to do a backup.  Snapsure 
uses checkpoints to avoid this issue.

My guess is...take a look at your NDMP savegroup reports and look at the 
area of where the index writes.  See if see messages about a stale file 
handler or a file that it is having a problem writing.  That could be the 
problem.

On another note, I have had another issue with indexes failing on our NAS 
backups because of a file names using non-English characters (russian 
letters).  Networker doesn't know how to handle those characters, so the 
savegroup report would show that file failing to save and also the index 
would fail to write because of the file had non-standard characters. This 
may be fixed in newer versions...I am still at 7.2.2 jumbo.

We have.

atar is recommended but dump has produced the same result; no file 
index.  Saveset is recoverable but not browsable.

Thank you,
