Joy,
Well, when we see this type of problem, what I do is run some sql to query the
database to get
the timestamps for each of the backups that was taken over the period in
question. If it is a
directory path problem you will have large time gaps when nothing is being
backed up.
If you use something like the sql below (substitute the correct time), this
should highlight the path that is the problem. If the time of the backups is
evenly spread over the whole period then you have some other performance issue.
SELECT HL_NAME,LL_NAME,BACKUP_DATE FROM BACKUPS -
WHERE NODE_NAME='your node name ' -
AND FILESPACE_NAME='your filespace name' -
AND BACKUP_DATE BETWEEN '2002-01-04 22:39' AND '2002-01-05 04:26'

Subject: Re: Archive problems
We did have the same problem with two Novell clients too. There are a lot of
files in the /usr filesystem, but I tailed the log file as the archive was
running and the directory that was archiving at the time was only 200 mb. I find
this very perplexing.

Joy,
Not an AIX person, but this sort of behaviour is commonly seen on Novell clients
when there
are very large numbers of files in a directory.
Could that be the case here.
Do you have performance issues opening files with other programs in /usr/

Subject: Archive problems
Does anyone have any information as to why /usr/ on an AIX 4.3.3- 4.1.4 TSM=
server, using TSM 4.1.3 client would take 52 hours to archive? It was al=
most like it was hung but then a few kbs would change every 30 min or so. =
All the other system files /var, /etc/, /home took a few minutes.
