mkCDrec is a linux based disaster recovery tool using CD, DVD, tape, NFS or network. After a disaster (disk crash or system intrusion) the system can be booted from the CD-ROM and one can restore the complete system as it was (at the time mkCDrec was run) with the command /etc/recovery/start-restore.sh Besides recovering the exact system to the same hardware (except for a new disk perhaps) there is the possibility to make a clone of just one disk. The command /etc/recovery/clone-dsk.sh allows one to restore a disk to another disk (the destination disk does not have to be of the same size as it calculates the partition layout itself). A thrid script, /etc/recovery/restore-fs.sh will restore only one filesystem to a partition of your choice, and the user can choose with which filesystem the partition has to be formatted. Linux 2.2.x, 2.4.x and 2.6.x kernels are supported, and if size of the kernel is not too big a boot floppy can be made, otherwise a 2.88 Mb boot floppy will be emulated on CD-ROM. MkCDrec supports ext2 , ext3, minix, xfs , jfs, reiserfs file systems, LVM and software RAID (multiple devices). Each file system is backed up as a compressed tar archive (including the tar log). The compress program used is the user's choice (compress, gzip, bzip2, lzop,...) But there is more: msdos, fat, vfat and ntfs mounted partitions are recognized and are saved as compressed dumps (on CD, tape, etc.) The user has the possibility to encrypt all backups with openssl if desired (see the Config.sh configuration file for more information).
