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)

AMSUNTAR(8) System Administration Commands AMSUNTAR(8)NAME
amsuntar - Amanda Application to interface with native tar utility available on solaris platforms
DESCRIPTION
Amsuntar is an Amanda Application API script. It should not be run by users directly. It uses Solaris bundled tar utility to backup and
restore data. Currenty ACLs from ZFS file system can only be backed up using the solaris supplied tar utility.
The diskdevice in the disklist (DLE) must be the directory to backup.
Solaris 10 supports Role Based Access Control(RBAC) which is enabled by default. To run backup operations using sun tar utility by under
privileged user like amandabackup, amandabackup user need to have proper roles and profiles, specially "Media Backup" profile/role. This
can be done using 'usermod -P "Media Backup" amandabackup' command.
PROPERTIES
This section lists the properties that control amsuntar's functionality. See amanda-applications(7) for information on application
properties and how they are configured.
BLOCK-SIZE
Optional tar read or write block size. The default is 256.
DIRECTORY
If set, suntar will backup from that directory instead of the diskdevice set by the DLE. On restore, the data is restore in that
directory instead of the current working directory.
EXTENDED-ATTRIBUTES
Include extended attributes in archive. The default is YES.
EXTENDED-HEADERS
Write tar file with extended headers. With this optiion the modification time is maintained with a granularity of microseconds,Long
file names and file sizes greater than 8GB can be archived. The default is YES.
SUNTAR-PATH
The path to the suntar binary. The default is set when Amanda is built.
LANG
Default LANG is "C". suntar require an UTF-8 LANG if you have UTF-8 filename and it is configured for extended headers. A good value
can be "en_US.UTF-8" if that locale is installed on your machine.
NORMAL
List all regex (Perl Regular Expression syntax) that are normal output from sun tar. These output are in the "FAILED DUMP DETAILS"
section of the email report if the dump result is STRANGE or FAILED. Default values:
is not a file. Not dumped$
same as archive file$
To treat one of these default patterns differently, specify it explicitly in a different property.
IGNORE
List all regex (Perl Regular Expression syntax) that amanda ignore. These output are never in the email report.
STRANGE
List all regex (Perl Regular Expression syntax) that are strange output from sun tar. The result of the dump is STRANGE if sun tar
produce a strange output. These output are in the "FAILED DUMP DETAILS" section of the email report. Default values:
: invalid character in UTF-8 conversion of
: UTF-8 conversion failed.$
To treat one of these default patterns differently, specify it explicitly in a different property.
ERROR
List all regex (perl Regular Expression syntax) that are error output from sun tar. All sun tar output that doesn't match a normal,
ignore or strange regex are error by default. The result of the dump is FAILED if sun tar produce an error output. These output are in
the "FAILED DUMP DETAILS" section of the email report. Default values:
: Permission denied$
To treat one of these default patterns differently, specify it explicitly in a different property.
