For those with backup tapes (and I just bought and installed a Seagate one for my FreeBSD box) I want to know how to get the most out of each tape by placing multiple backups on each tape (potentially 20GB). Please correct me if I'm wrong:
First, retension the tape:
# mt retension
next, turn... (3 Replies)
Currently am running the backup command for AIX 5L and see that the tape is rewinding after the completion of the back.

What can I do to stop allow the backup to rew after the completion of this job? Any thoughts?
Thanks again. (2 Replies)

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... (5 Replies)

Hello,
I need to be able to encrypt LTO tapes that our AIX writes to for backups.
We have a tape library (IBM TS3100) that our AIX host uses to write to LTO6 tapes. We then take those tapes off-site and restore to another AIX system using a 3580-H6S LTO6 tape drive - this is a very simple... (3 Replies)

amdump
AMDUMP(8) System Administration Commands AMDUMP(8)NAME
amdump - back up all disks in an Amanda configuration
SYNOPSIS
amdump [--no-taper] [-o configoption...] config [host [disk...]...]
DESCRIPTION
Amdump is the main interface to the Amanda backup process. It loads the specified configuration and attempts to back up every disk
specified by the disklist(5). Amdump is normally run by cron.
The command optionally takes a set of DLE specifications (see amanda-match(7)) to narrow the DLEs that will be dumped. All disks are dumped
if no expressions are given.
If a file named hold exists in the configuration directory, amdump will wait until it is removed before starting the backups. This allows
scheduled backups to be delayed when circumstances warrant, for example, if the tape device is being used for some other purpose. While
waiting, amdump checks for the hold file every minute.
In some cases it is desirable to dump all Amanda clients to holding disk without writing anything to storage media. The --no-taper option
instructs Amanda to not start the taper, and thus enter degraded mode immediately.
See the amanda(8) man page for more details about Amanda.
OPTIONS
host [disk]*
Specify the host and disk on which the command will work -- see the description of DLE specifications in amanda-match(7).
-o configoption
See the "CONFIGURATION OVERRIDE" section in amanda(8).
EXAMPLE
Here is a typical crontab entry. It runs amdump every weeknight at 1 a.m. as user bin:
0 1 * * 1-5 bin /usr/local/sbin/amdump daily
Please see the crontab(5) or crontab(1) manual page for the correct crontab format for your system.
MESSAGES
amdump: waiting for hold file to be removed
The "hold" file exists and amdump is waiting for it to be removed before starting backups.
amdump: amdump or amflush is already running, or you must run amcleanup
Amdump detected another amdump or amflush running, or the remains of a previous incomplete amdump or amflush run. This run is
terminated. If the problem is caused by the remains of a previous run, you must execute amcleanup(8) and then rerun amdump.
EXIT CODE
The exit code of amdump is the ORed value of:
0 = success
1 = error
2 = a dle give strange message
4 = a dle failed
8 = Don't know the status of a dle (RESULT_MISSING in the report)
16 = tape error or no more tape
