I noticed on a couple Solaris machines with TIR enabled, it causes many
client process errors (50) and (41, network connection timeouts), but
when I disable it, the backups complete successfully.

=20

The way the server was setup is to keep the TIR information for only a
single day, which is quite useless for the most part.  Does anyone have
any good or outstanding reasons for using TIR?

=20

The way I currently have most backups laid is as follows:

=20

WEEKLY FULLS

DAILY DIFFERENTIAL-INCREMENTAL (except on FULL DAY)

=20

>From the manual, it states:

(check page 87 of the unix manual) (the pic wouldn't fit)

=20

Ultimately, using TIR seems like it provides the best "sync" for the
end-user, in that he or she does not have to re-delete files that they
have already deleted, but since the information in my configuration is
only kept for a day, that probably does not merit using it at all, does
it?

=20

Any comments?

=20

Thanks,

Justin.
