I'm on a VAXcluster (VMS 6.2) with a VAX 6000-410 and some
3100 Workstations and a MicroVAX.
During weekly incremental backup the following command is
automatically created by a DCL script and then executed:
$ backup /rec /ignore=(inter,label) /list=USER_BACKUP.LIST -
! the command
/BLOCK=65534 /COMMENT="bck week tape 30"
(The 2nd, 4th, 6th line have been wrapped around here to get it
Problem is: Although it is specified "/SINCE=BACKUP" and the last
BACKUP/REC has been done one week before --- as every friday ---
the command will backup ALL files, regardless if they have been
altered during this week or not.
[AP1.GAYMANN]LOGIN.COM;8 has been backed up.
dir/date=(mod,backup) login.com gives:
LOGIN.COM;8 5-APR-1994 14:31:38.01 11-MAR-1996 14:19:21.15
So the backup has been recorded (as is done every week...)
although the file has not been altered since 2 years!
I have changed the position of the "/since=backup" qualifier in
the backup command because the documentation says it's important,
but this did not change anything.
The last time it worked O.K. was one year ago with VMS 6.0 and
an IBM 3480 Backup tape drive.
We did not use this dcl routine for backups for one year, because
the drive broke.
Now we use it again, have changed to VMS 6.2, changed the node
BACKUP is running, from the microvax to a station3100, and have
"cleaned up" the routine at some places where errors were located,
By the way, the files to be backed up are located on the VAX 6000-410.
Can anyone shed some light on it?
