Personaly I found a way for myself to produce a consistent backups: 1. have an additional filesystem /backup 2. mount /backup 3. sync your changed files to /backup (I usually do this with rsync, YMMV) 4. umount /backup 5. mount /your_backup_media 6. dump -0auf /your_backup_media /dev/<backup> However it need some preparation done beforehand, preferably on system install. this way you will be able to dump live filesystems without having to reboot your server. -- With best regards, Gregory Edigarov
