Here's the detail Tim asked for:
The main distinction between the daily, weekly and monthly backups is
how long the data needs to be retained.
Most of our clients run a full once a week and an incremental each other
day. The incremental backups are the daily backups. The full backups
are either weekly or monthly depending on the date. The first week of
the month, the full backups are monthlies. The remaining times the full
backups are weekly backups.
For example, a clientA may run full backups on Monday. The schedules
for clientA would be:
- daily - incremental all, skip Monday
- weekly - full Mondays, skip the first Monday of the month
- monthly - full the first Monday of the month, skip each other day
The daily, weekly and monthly backups each back up to different pools.
Pool selection is based on the group. Each group is named with a daily,
weekly or monthly extension. Since each type of backup has a different
retention, this keeps data with the same retention scheme on the same
media.
We've had this configuration in place for about 5 years through several
versions of NetWorker. If there is a way to simplify things, I'd love
to hear it. Although this has worked, it has always seemed like there
had to be an easier way.
Thanks.

Can you explain more about what your backup schedule looks like? I ask
because I'm wondering if it might not be possible to simplify some of
your
scheduling and completely avoid this problem, but I won't know for
certain
until I know more about what your scheduling needs are.
I can tell you that we're at 7.4.2 on the server and still have a bunch
of
clients that are running 7.2.2, and we're not seeing this issue.
However, we're not running hundreds of skips a night either.
