Hey guys complete n00b here so I'll try my best at explaining.
I'm creating a backup and restore utility and decided to use tar. I create a backup folder in each user's account and when backing up (say word processing files), I use the following:
When I go to extract, though, I'm using the following command:
Problem is that this creates a /home/user/wp/ path IN the backup directory, as well as extracting the files in there. What I would like to know is how to fix this so that the extracted files from wpbackup.tar are put back into the /home/user/wp/ directory.
That's my primary aim^, however if I can't get that working is there any way to extract the contents of the tar file into the directory it was created in (/backup), so I can just copy them across to the user's appropriate directory?

Hi,
I'm using a tar command
tar -xOvf /home/mytar.tar

without extracting files to the disk.
Is this the best way to achieve it?
Thanks,

In the bash below each .tar.bz2 (usually 2) are extracted and then the original .tar.bz2 is removed. However, only one (presumably the first extracted) is being removed, however both are extracted. I am not sure why this is? Thank you :).

updadmin(8) System Manager's Manual updadmin(8)NAME
updadmin - Invokes the Update Installation Cleanup utility to remove or archive backup files created by an Update Installation
SYNOPSIS
/usr/sbin/updadmin
DESCRIPTION
The updadmin command invokes the Update Administration Cleanup utility, which removes or archives the backup files that were created by
an Update Installation process. There are no flags or options associated with this command. Running this utility is an optional step after
performing an Update Installation, but it is recommended if you want to recover disk space being consumed by these backup files.
The backup files that are created by an Update Installation have these extensions: *.PreMRG - A file saved to a extension is a backup copy
of a customized protected system file. System files in this category are system files that are expected to be customized by users, for
example, /etc/passwd and /etc/hosts. If the automatic merge process fails to merge the new version of the file with your customizations to
the file, your customizations must be merged manually into the new version of the file when the Update Installation is complete. The
*.PreMRG version is a copy of the file as it existed before the Update Installation and only will be present if the automatic merge fails.
*.PreUPD - A file saved to a extension is a backup copy of a customized unprotected system file as it existed before the Update Installa-
tion. System files in this category are system files that are not expected to be customized by users, for example, /usr/bin/X11/netscape.
If an unprotected system file is altered in any way, customizations must be merged manually into the new version of the system file when
the Update Installation is complete.
When you are finished merging your customizations into the new version of the file, these backup files no longer are needed, and they can
be removed or archived.
The Update Installation Cleanup utility gives you the option to archive or remove all backup files, or to select only the files you want.
You are prompted to enter an archive destination if you decide to archive the files.
The Update Installation Cleanup utility uses the tar(1) command to create the archive, and the archive destination can be any archive des-
tination supported by the tar command, including tape devices. The default archive location is the backup.tar file in the /var/adm/update/
directory. You can use any file name you want, but if you want the file to have a extension, you must enter it as part of the file name. If
the file name exists, it is overwritten. You have the option to compress the archive file with the gzip utility; if you do, a extension is
appended automatically.
Unless you compress the archive file, the space savings realized by archiving to a tar file on disk will be only in moving the files from
the / (root), /usr, or /var file systems to the file system containing the archive. To save disk space, archive the files to tape.
To archive to a tape device in tar format, enter archive destinations similar to the following: /dev/tape/tape0c - archives to a default
density rewind tape (with compression) /dev/ntape/tape0_d0 - archives to a nonrewind tape device 0. The _d0 suffix specifies the density.
If you are archiving to a nonrewind tape device, it is recommended to use a brand new or erasable tape.
On systems capable of graphical display, the updadmin command invokes a graphical user interface to the Update Installation Cleanup util-
ity. On systems that are not capable of graphical displays, a text-based, menu-driven user interface is invoked. The Update Installation
Cleanup utility is also available as a task from the SysMan Menu.
To view the online help for the Update Installation Cleanup utility without running the utility, use the following command: #
/usr/dt/bin/dthelpview -h /usr/dt/appconfig/help/C/updadmin.sdl
RESTRICTIONS
You must have root privileges to use the Update Installation Cleanup utility.
If your system has not been updated to the next version of the operating system by the Update Installation process, the Update Installation
Cleanup utility cannot be invoked.
