System backup

[Roland Piette]

Hi everybody,

1) Under HP-UX exists a tools to make an system backup known as Ignite wich create a bootable tape.

Is it exist any tools under RH wich gives the same facility ?

2) I another way I try to use the dump (replacement of fbackup) command to backup file systems but I received this following messages :

DUMP: Date of this level 0 dump: Thu Jan 19 22:15:01 2006
DUMP: Dumping /dev/mapper/VolGroup00-LogVol00 (/) to /dev/st0

DUMP: ACLs in inode #983078 won't be dumped
.....

The log file contains more than 112900 times of this last line !!!

Witch tools can backup safely ACL's ?
What can happen if I have to restore files from this backup ?

Thanks

You should not use dump for backup on Linux, it has problems with buffers that may cause that your data cannot be restored. Use the star command to backup the data, star supports ACL's and SELinux attributes.

SystemImager and Mondo rescue can generate a backup of your system to network or cd media.

You can try this excellent opensource project for backs up your linux server.

Hi Ivan and Sergejs,

Thanks for your repliues.

I haven't found the command star in the man pages neither in the file system.

What do you think about amanda, wich is in the RH distribution. I would like to minimize the package installed on this server. So I give my prferrence to the standard distribution.

Star is an excelent and simple command but is not installed by default, install from the distribution cd or use red hat network.
