This Live CD aims to provide all the important pieces of software for system recovery and administration. This page shows the most important tasks.
sfdisk is a tiny program which saves the partition table to a regular file and only takes a few seconds.
As an initial step for system recovery before making things worse.
sfdisk -d /dev/sda > sda.partTable
Copy the backup to another hard disk, removable media (thumb disk, floppy or CD) or ftp it to another computer.
cat sda.partTable | sfdisk /dev/sda will restore partition table.
This command is very dangerous, because it overwrites the existing partition table
Before restoring, you should back up the current version, even if it seems to be damaged. This would allow you to undo the restoration.
SystemRescueCd comes with a lot of archive programs. You can use zip/unzip for
the ZIP format, and unrar for the RAR format. Even the new 7zip is supported
Dar is an archiver similar to tar, but it is more powerful. Even when using compression, dar does not have to read the whole backup to extract one file. This way, if you just want to restore one file from a huge backup, the process will be much faster than using tar. Dar first reads the catalogue (i.e. the contents of the backup), then it goes directly to the location of the saved file(s) which you want to restore and then proceeds to restoration. In particular using slices dar will ask only for the slice(s) containing the file(s) to restore. But you can also restore all files from an archive, dar will then read sequentially without seeking into the file, except for the first and last slice, dar will not ask twice for the same slice.
This CD provides a gparted which is a graphical partition editor and aims to be
very easy to use, and very powerful. You can run gparted from the xorg
graphical environment. Please refer to the boot process if you do not know how
to work in xorg. You can run GParted by typing this
gparted, or from the icons on the desktop.
