The trick for getting a "clean" store is to subtract out the files that show
up in the open for writing mode via an indirect store file. For static files
this is quite easy. For others it might mean negating an entire sequence of
files. For example system log file numbers vary from backup to backup, thus
to eliminate this file you can
 LOG####.PUB.SYS.

WARNING: Subtracting files from a "full backup" is a dangerous proposition
and should only be done by competent system administrators! It is not the
intention of this method to subtract out files that would have otherwise
been written to tape other than system log files.

The reason I mentioned this is that using this method it is very easy to
subtract out entire groups and accounts. While this may speed up the backup
process it also means that you no longer have a single full backup set.

An indirect store file might look like this (YMMV):

@[log in to unmask]@
-DSTLGTAB.PUB.SYS
-DSTLID.PUB.SYS
-DSTRINS.PUB.SYS
-DSTWELC1.PUB.SYS
-DSTWELC2.PUB.SYS
-FPROTECT.PUB.SYS
-HPGID.PUB.SYS
-HPGIDNX.PUB.SYS
-HPUID.PUB.SYS
-HPUIDNX.PUB.SYS
-JMATFILE.PUB.SYS
-LOADLIST.PUB.SYS
-LOG####.PUB.SYS
-LOG4ONLN.PUB.SYS
-MEMLOG.PUB.SYS
-NMLG####.PUB.SYS
-RUNOR.PUB.SYS
-SLORE.PUB.SYS
-TURBODBS.PUB.SYS
-TURBOLKT.PUB.SYS
