Need help deciphering client trace info
2000-02-14 13:09:18
I've been trying to get one of our Novell 4.1.1 clients ( ADSM client level
3.1.0.7) to get thru an incremental backup of all data in a reasonable
amount of time. It had been taking around 24 hrs. To determine where the
problem is, I ran backups of subsets of data, then took the longest running
subset and ran backups both incrementally and selectively to see if there
was a difference. And WOW, was there. I posted a question here several
weeks ago asking for ideas why this might be. One suggestion I received
was to turn on client tracing using "traceflags instr_client_detail" to
help further determine the problem. I did this, but I don't see in the
ADSM Trace Facility Guide how to interpret the resulting trace info. Any
help would be appreciated. Here is both the activity log and trace info
for both the selective and incremental runs:

Obviously the transaction time for the incremental run is huge. Can anyone
tell me what this time accounts for? Any other observations or
suggestions? TIA.
