Tape backups: do you always verify them after doing them ?
It may seam a bit odd that I ask this question.
After you have done your backups to tapes, do you verify the content of the tapes ?
- never
- sometimes
- always
The reason I am asking is that here in the office, all the backup procedures include verifying the content of the tapes (no matter if it is a savevg, mksysb or Tar). The only reason I can think of for doing this is that the tapes/drives here are not 100% reliable as we sometimes get errors on verifications (5-10% of the times). If they were 100% reliable, then I do not see why we would have to verify all the backups. It just adds up to the amount of work to do during those days.

amreport
AMREPORT(1) General Commands Manual AMREPORT(1)
NAME
amreport - generate a formatted output of statistics for an Amanda run
SYNOPSIS
amreport [ config ] [ -l logfile ] [ -f outputfile ] [ -p postscriptfile ]
DESCRIPTION
Amreport generates a summary report of an amanda(8) backup run. If no configuration name is specified, amanda.conf is read from the cur-
rent directory.
See the amanda(8) man page for more details about Amanda.
OPTIONS
config Name of the configuration to process.
[-l logfile]
Name of the log file to parse to generate the report. If a log file is not specified, it defaults to the file:
logdir/log
where logdir is the log directory defined in amanda.conf.
[-f outputfile]
Normally, amreport sends the report via e-mail to the mailto user as defined in the amanda.conf file. If outputfile is specified,
then the report is put in outputfile.
[-p postscriptfile]
Send the postscript output to the file postscriptfile instead of to the lpr(1) command. This option has an effect only if the lbl-
templ directive is specified in amanda.conf.
LABEL PRINTING
Amanda can print postscript labels describing the contents of tape(s) written in a run. The labels are designed to be folded and inserted
into the tape case along with the tape or hole punched and put in a 3-ring binder. Various label templates are provided to format data for
different tape sizes.
The information printed varies slightly between label templates due to size constraints. Labels contain one line for each host/file-system
pair and may also contain the file number on the tape, the level of the dump, the original size of the dump and the size of the (possibly
compressed) tape file.
Add the lbl-templ parameter to the tapetype definition in amanda.conf to enable labels. If you don't add this line to your tapetype defi-
nition, amreport will not print tape labels.
You may use the printer keyword in amanda.conf to print to other than the system default printer.
TEMPLATES
Amanda provides label templates for the following tape types. These are pretty generic labels and should be easy to customize for other
tape types or particular site needs.
* ExaByte 8mm tapes
* DAT 4mm tapes
* DLT tapes
* 3-ring binder
The 3-ring binder type is the most generic. It may be used to make a hardcopy log of the tapes.
