Richard,
Are you doing reorg or reorg while active?
We run a similar process using reorg while active.
Reorg will be quicker, but requires exclusive use of the files, and I believe will cause the index rebuilds.
Reorg while active will be longer, users can remain on, index rebuilds are less, done concurrently.

Subject: Backups taking longer after reorg
All,
First, let me wish everyone a happy new year. I hope that each of you is blessed this year with good health and prosperity. Now to my issue - I wrote a program that scans through libraries and reorgs files that have many deleted records. Sounds reasonable enough.....However, since running this program, my backups are running much longer. Why would this be? Is there something that I can do to get the time needed to save these libraries back to a reasonable timeframe?
I have considered saving the libs to a save file and making the system available while backing the save files up to tape (which I'm assuming would be faster given the I/o rate of disk vs. tape). But I'm perplexed as to why the reorg would add time to my backup.
Any thoughts/suggestions are much appreciated.
Sincerely,
Richard Reeve
