A question we are often asked is "How can I make my backup go faster?" The simplest answer is "Don’t back up so much." While this may sound like a sarcastic answer, really it isn’t. The less data you back up the faster the backup will go. This can be accomplished in several ways.
First, clean
up the system. The less data you carry on the system the less you
will have to back up. More importantly, it is less data to restore
if you need to re-install. Look for files that have not been accessed
in over a year, memory dumps (listf @mem.dat.telesup), test copies
of production databases, old system log files (LOG####), and old
network log files (NMLG####). You can also look for old Editor work
files (K#######) or Quad work files (Q#######).
For those users who don’t own a copy of MPEX we have several utilities
in the ESP account to help search for files that can be eliminated.
BIGFILES will help identify the largest files on your system
and show you their create, access, and modify dates. The latest
version, which supports HFS files, can be downloaded from
http://www.beechglen.com/mpe/downloads.html.
To manage system log files we provide the program LOGPRGX.PUB.ESP.
LOGPRGX will purge all system log files prior to a date that you
specify.
Another method for speeding up a backup is using faster tape drives,
or to use several drives simultaneously. This is known as parallel
backups. Tape drive speed is commonly the limiting factor in increasing
the speed of a backup. With MPE/iX Release 5.5, HP changed the product
structure of the TurboStore product where the parallel tape drives
option is now included free of charge. A store command to simultaneously
store files to ldev 7 and ldev 8 would look like this:
:file drive1;dev=7
:file drive2;dev=8
:store @.@.@; ; storeset=(*drive1),(*drive2);show;directory;progress
