anyone setup and using a scsi or ide, external or internal vxa-1 tape drive connected to the sme server?
we have a external scsi and would like to hook it up to ours as backup over the network doesnt allow a full backup, including system and email and such.
here's ide instructions which i will take a deeper look at:

How to install an IDE Tape drive on e-smith 4.x/SME 5.x
--------------------------------------------------------------------------------
Problem:
You need an inexpensive, easy to use, tape backup solution for your e-smith server and gateway.
Recommended Solution:
IDE TBU Hardware:
Seagate STT220000A Hornet 10/20GB IDE Tape Drive (highly recommended)
Ecrix VXA-1 33/66GB IDE Tape Drive
Step 1- Hardware Set-up:
Place your hard drive(s) on IDE0 connected to an 80 wire, 40 pin UDMA IDE cable. Connect your tape drive and CD-ROM on IDE1 using a standard 40 pin IDE cable.
Step 2 - Using SSH:
Follow your server's manual and use an SSH client to connect to the server command line. Some good SSH clients are puTTY, MindTerm or TeraTermSSH.
Step 3 - Testing your tape drive:
To test your tape drive issue the command:
# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 512 bytes. Density code 0x47 (unknown to this mt).
Soft error count since last status=0
General status bits on (1010000):
ONLINE IM_REP_EN
Step 4 - Performing a backup/restore:

How-To use the flexbackup tape program
--------------------------------------------------------------------------------
Using the e-smith-manager's Backup or restore panel you may set-up your e-smith server to perform a scheduled daily full backup. Also, under the Backup or restore panel you may restore your e-smith server and gateway, configuration and user data files from a backup tape.
The command line must be used if you want to restore the entire tape or individual files. This How-To guide will assist you in performing the command line functions.

How to perform a full backup
To perform a full backup, you may use the e-smith-manager to schedule a backup session. Alternately, to execute an immediate backup you may use the command script:
. /sbin/e-smith/backup
NOTE: Do not run 'flexbackup -fs all' to perform a backup. The script /sbin/e-smith/backup is preferable as it performs many additional functions required to completely backup an e-smith server.
How to set flexbackup to always perform an erase
/sbin/e-smith/db configuration setprop flexbackup erase_rewind_only false
/sbin/e-smith/signal-event console-save
This will set flexbackup to erase the tape prior to running the backup. This is known to help some hardware configurations where i/o errors are encountered.
How to list and view the contents of a tape
First let's create a working directory /root/flexbackup with the following command:
mkdir /root/flexbackup
To list and view the contents of a tape you may issue the commands shown below:
cd /root/flexbackup
/bin/mt -f /dev/nst0 rewind
/bin/mt -f /dev/nst0 fsf 1
/usr/bin/flexbackup -list > /dev/null
/bin/ls -l /root/flexbackup/flexbackup.list.log
/bin/mt -f /dev/nst0 rewind
/usr/bin/pico /root/flexbackup/flexbackup.list.log
Alternately you could create a script including these commands and launch the script from the command line. As an example if you created the script named '/root/flexbackup/flexbackup-list' you would launch the script by entering:
. /root/flexbackup/flexbackup-list
How to perform a full -extract
To perform a full restore you may issue the commands shown below:
cd /
/bin/mt -f /dev/nst0 rewind
/bin/mt -f /dev/nst0 fsf 1
/usr/bin/flexbackup -extract
/bin/mt -f /dev/nst0 rewind
Alternately you could create a script including these commands and launch the script from the command line. As an example if you created the script named '/root/flexbackup/flexbackup-extract' you would launch the script by entering:
. /root/flexbackup/flexbackup-extract
How to perform a selective -extract
To perform a command line restore, create a file which contains a list of all files/directories to be restored. As an example, lets assume you have an ibay name 'data' and subdirectories named '/acct/1999' and /acct/2000 that you want to restore. You could create a file named '/root/flexbackup/extract-list' which contains the following lines:
/home/e-smith/files/ibays/data/files/acct/1999
/home/e-smith/files/ibays/data/files/acct/2000
To perform the restore you would issue the command:
cd /
/bin/mt -f /dev/nst0 rewind
/bin/mt -f /dev/nst0 fsf 1
/usr/bin/flexbackup -extract -files /root/flexbackup/extract-list
/bin/mt -f /dev/nst0 rewind
NOTE: The first line cd / will restore your files to their original locations. To restore to the current directory, remove the 'cd /' entry.
Alternately you could create a script including these commands and launch the script from the command line. As an example if you created the script named '/root/flexbackup/flexbackup-extract-list' you would launch the script by entering:
. /root/flexbackup/flexbackup-extract-list
How to perform an interactive restore
To perform an interactive restore you may issue the commands shown below:
cd /
/bin/mt -f /dev/nst0 rewind
/bin/mt -f /dev/nst0 fsf 1
/usr/bin/flexbackup -restore
/bin/mt -f /dev/nst0 rewind
Alternately you could create a script including these commands and launch the script from the command line. As an example if you created the script named '/root/flexbackup/flexbackup-restore' you would launch the script by entering:
. /root/flexbackup/flexbackup-restore
NOTE: The first line cd / will restore your files to their original locations. To restore to the current directory, remove the 'cd /' entry. Remember the restore includes the full path. As an example if your current directory is /root and you restore /home/e-smith/files/ibays... the restore will be found under /root/home/e-smith/files/ibays...
Available commands when running flexbackup - restore in interactive mode are:
ls [arg] - list directory
cd arg - change directory
pwd - print current directory
add [arg] - add arg' to list of files to be extracted
delete [arg] - delete arg' from list of files to be extracted
extract - extract requested files
setmodes - set modes of requested directories
quit - immediately exit program
what - list dump header information
verbose - toggle verbose flag (useful with ls'')
prompt - toggle the prompt display
help or ?' - print this list
If no arg' is supplied, the current directory is used
--------------------------------------------------------------------------------
As a final note, as an easy way to keep all of these flexbackup scripts during an e-smith upgrade, I would suggest you move them all to an ibay location and run them from the ibay location instead of /root. Of course you will have to edit the scripts as appropriate for your actual ibay location. Since the e-smith-manager tape restore function restores all the ibays you'll be ready to go immediately after an e-smith-manager restore :-)
