Unable to verify data on DDS-3

[Philip Horan]

Pieter I have noted the WEEKLYBACKUP backs up using:
tar -cvB -C /mtms . -C /mtmsdb . -C /mtmsdb1 . -C /mtmsdb2/mtmsdb1

The AUTOBACKUP uses:

tar cvB -C /mtmsdb1 . -C /mtmsdb2/mtmsdb1

Whats the difference between -cvB and cvB?
Thanks,
Phil.

Pieter the backup is scheduled for 1900. I have just run command suggested to see what script was running, it returned;

mtmsadm 6559 6601 0.0 20:05:08 ttyp1 0:00.01 grep rmt0

regards,
Phil.

Pieter the backup completed as expected. I received email notification as follows:

I ran: tar tvf /dev/rmt0h to verfy data has been written to the tape. The final few entries are below:

As you can see the files have a last modified date = to yesterday July 14.

I will monitor this evening as I only have 1 previous good backup (there may just be an issue with the Weekly?).

Many thanks for keeping pace with this post.
Phil.

Hi Phil,
apearently at 19:07 the process was not yet accessing the tapeunit, so the grep for rmt only returned your own grep-command.
the first line of the mail confirms this:
"Mon Jul 14 19:50:00 BST 2008 Start of CRON processing"
which matches this enry in the crontab of user mtms :
"50 19 * * 1-4 /mtms/bin/Nightly.jcl > /mtms/tmp/cron.out"
wich in turn starts "/mtms/bin/AUTOBACKUP"

as i stated before a "#" normally denotes a comment in shell scripts, but the filenames ending with ".jcl" and other commands within these scripts suggest you are using a script-environment other than sh or ksh wich DOES reads and interprets the lines starting with "#"

in the weekly script all lines adressing mail are "#"-ed, in the autobackup they are not!
so maybe it does run, but doesn't mail!

the difference between -cvB and cvB is "historical". originally "-" was used to specify options on commands.
in later tru64 versions the options can be specified without this character.
see attached note from "man tar".

Thanks Pieter. Although I am unconvinced I have heard the last of this issue I shall award points as they have been well earned!
Many Thanks,
Phil.

[Pieter 't Hart]

thanks in advance for points.
my hat will change as this will tip me over the edge from baseball-cap to graduate-cap.

[Philip Horan]

Ha! I can only dream of owning a hat!!
Well deserved I am sure.
Kind Regards,
Phil.
