Backups
=======

Policy
------

o Local drives are not backup up.
o /home1 should be backup up on a daily basis.
o We use dump because it is a reasonable option and is what Dan and 
  Alan already use with other systems.
o Daily backup is based on weekly tape change (at least until the disk
  gets too full).

Backup seem to be working nicely. Changing tape on Monday each week and 
intend to rotate 4 or 5 tapes. Used restore to list files on the tapes from
last week and that seems good.

===============================================================================

14Jun98 - Simeon Warner

Set up a crontab script for full backup on Monday night followed by a
sequence of daily backups through until Sunday which will allow recovery
requiring a maximum of 3 restore operations.

For some reason doesn't work... exits with lots of lseek errors!

13Jul98 - Simeon Warner

Didn't work before becasue the version of dump I had could not handle more
than 2GB in a partition. Replaced dump-0.3-10.i386.rpm (RH5.0 dist) with
dump-0.3-13.i386.rpm (RH5.1 dist, no errata noted as of 13Jul98). Seemed
to work okay with test backup. Crontab is:

#root crontab for pop01
#
#
# Format of lines:
#min    hour    daymo   month   daywk   cmd
#
00	01	*	*	1	echo "From root crontab on pop01" | mail -s "CHANGE TAPE ON PoP" simeon@physics.syr.edu > /dev/null >2&1
