This will be covered elsewhere im sure but i just cant seem to find my exact issue.
I want to backup my systems using tar, command is:
When i include the / directory it also tar's the /lib /sys /proc /dev filesystems too (and more but these seem to be problem directories.)
Although i have never tried to restore the /sys /proc and /dev directories I have not seen anyone mention that your cant restore /lib but when i tried the server crashed and would not even start the kernel (not even in single user mode).
Can anyone let me know why this happened and provide a more comprehensive list of directories than the 4 mentioned as to what should and shouldn't be backed up and restored? Or point me to a useful site that might explain why you should or shouldn't backup each one?
I backed up a unix database using
"tar -cvf /dev/rmt1 -N 800 /*"
Normally I would restore this using
"tar -xvf /dev/rmt1 -N 800"
This is reporting an error about
"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)

tdbbackup
TDBBACKUP(8) System Administration tools TDBBACKUP(8)NAME
tdbbackup - tool for backing up and for validating the integrity of samba .tdb files
SYNOPSIS
tdbbackup [-s suffix] [-v] [-h]
DESCRIPTION
This tool is part of the samba(1) suite.
tdbbackup is a tool that may be used to backup samba .tdb files. This tool may also be used to verify the integrity of the .tdb files prior
to samba startup or during normal operation. If it finds file damage and it finds a prior backup the backup file will be restored.
OPTIONS -h
Get help information.
-s suffix
The -s option allows the adminisistrator to specify a file backup extension. This way it is possible to keep a history of tdb backup
files by using a new suffix for each backup.
-v
The -v will check the database for damages (currupt data) which if detected causes the backup to be restored.
COMMANDS
GENERAL INFORMATION
The tdbbackup utility can safely be run at any time. It was designed so that it can be used at any time to validate the integrity of tdb
files, even during Samba operation. Typical usage for the command will be:
tdbbackup [-s suffix] *.tdb
Before restarting samba the following command may be run to validate .tdb files:
tdbbackup -v [-s suffix] *.tdb
Samba .tdb files are stored in various locations, be sure to run backup all .tdb file on the system. Important files includes:
o secrets.tdb - usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba.
o passdb.tdb - usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba.
o *.tdb located in the /usr/local/samba/var directory or on some systems in the /var/cache or /var/lib/samba directories.
VERSION
This man page is correct for version 3 of the Samba suite.
AUTHOR
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
