The Linbox Rescue Server FAQ
Q: How do you backup a fat/ntfs partition ? I get an "unsupported or corrupted file system" error.
A: The LRS GPL edition can make disk images of free OSes. For differences between to free and commercial editions of the LRS, please refer to this page: http://www.linbox.com/ucome.rvt/any/en/Produits/LRS/llrs/comparaison.tmpl
Q: Where is the documentation ?
A: The latest documentation can be found here. That's the "commercial edition" documentation, but everything is applicable to the "GPL edition", except the "Post-installation" chapter, and multicast restorations.
Q: Why cannot I make a live backup of the system ?
A: If you make a live backup of your system, you cannot be sure that databases or open files will be properly backed up. So why making backups which cannot restore your system to a usable state ? With the LRS system backup, you make a snapshot of your hard disk, and you're sure that it will boot after restoration. As a supplement, if you want to backup frequently changing files, you should use the 'Files Backup' LRS module.
Q: Can I save the disk images to tape ?
A: Yes. You have to backup two directories: /tftpboot/revoboot/images (which holds shared images), and /tftpboot/revoboot/imgbase (which holds local backups).
Q: Is my server supported by the LRS system backup ?
A: Frequent updates are done to support latest PCs. A non-exhaustive list of supported hardware is available on Supported Hardware page.
Q: Is my Linux distribution supported by the LRS system backup ?
A: Most Linux distributions can be backed-up by the LRS since LVM, ext2, ext3, reiserfs, and xfs is supported by the LRS. This includes, but it is not restricted to : Debian Woody/Sarge/Etch?, Red Hat Enterprise Server 3.x 4.x, Suse Linux Enterprise Server 10, OpenSuse, Centos 4.x, etc. Unlike many of disk imaging tools, LVM is fully supported: LVM partitions are not saved using a 'dd', and only really used HD sectors are saved.
Q: How can I extend /tftpboot to my whole disk ?
A: Please read the doc
Q: Can I extend /tftpboot on others disks ?
A: Quick answer: yes, but don't do this. Long answer: yes, but do this only on RAID1 or RAID5 volumes, or RAID-with-redundancy volumes. NOT on RAID0 or single drives.
