Hello all,
today I've been sitting at work and upgrading a very-very-very old
server with RedHat Linux 6.2 installed up to CentOS 3.8. The process
went smoothly, as it is not the first time I was doing the things like
this. Just after upgrading I went to rpm -qai list and got an
interesting observation: there are at least two "tar" utilities installed
on the system.
One is tar, and second is star.
[root@devel mrtg]# rpm -qi star
Name : star Relocations: (not relocatable)
Version : 1.5a08 Vendor: CentOS
Release : 4 Build Date: Вск 29 Фев 2004 04:54:14
Install Date: Пнд 13 Ноя 2006 09:38:38 Build Host: centos3.wellhouse
Group : Applications/Archiving Source RPM: star-1.5a08-4.src.rpm
Size : 336744 License: GPL
Signature : DSA/SHA1, Втр 16 Мар 2004 01:48:38, Key ID 7049e44d025e513b
URL : http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/star.html
Summary : An archiving tool with ACL support
Description :
Star saves many files together into a single tape or disk archive,
and can restore individual files from the archive. Star supports ACL.
[root@devel mrtg]# rpm -qi tar
Name : tar Relocations: (not relocatable)
Version : 1.14 Vendor: CentOS
Release : 4 Build Date: Пнд 21 Фев 2005 18:58:37
Install Date: Срд 05 Апр 2006 19:48:51 Build Host: bhrama.build.karan.org
Group : Applications/Archiving Source RPM: tar-1.14-4.src.rpm
Size : 824393 License: GPL
Signature : DSA/SHA1, Вск 27 Фев 2005 00:39:26, Key ID a53d0bab443e1821
Packager : Karanbir Singh <kbsingh@xxxxxxxxxx>
URL : http://www.gnu.org/software/tar/
Summary : A GNU file archiving program.
Description :
The GNU tar program saves many files together in one archive and can
restore individual files (or all of the files) from that archive. Tar
can also be used to add supplemental files to an archive and to update
or list files in the archive. Tar includes multivolume support,
automatic archive compression/decompression, the ability to perform
remote archives, and the ability to perform incremental and full
backups.
If you want to use tar for remote backups, you also need to install
the rmt package.
I would like to know, what are the differences between them? Which
one should I use in the future? Is star compatible with amanda backup
suite (I use amanda as a main backup software solution for our
production environment servers)?
Also, there may be other tar-like/compatible utilities shipped
with CentOS3/4 that I simply don't know about. It would be great, if
somebody will provide me with info (or a link to a place) about such
utilities, and with a comparison between them all. Thanks in advance.
