Backup: dump x tar
 

Hi all !
I'm new on Linux and I'd like to know what is the best command for backup (dump or tar) ? I've heard that dump is only trustworthy when used in single user mode. Is it correct ? Anyway, I'm using the follwing command to backup my system: "dump -0uf /dev/st0 /". The problem is that I've got four file systems. How can I backup those 4 file systems with a single command line ?

Thanks,
Augusto

Linus said that now dump should not be working reliably on ext3.

Go for tar. Portable, file-system independant, can compress.

I usually use tar and cpio but TAR is by far my favorite it does backups the best on all kinds of filesystems ext2, ext3, reiserfs ,ufs even msdos and ntfs surprisingly. Again would go for tar.
