Partition table backup
Create a partition tables backup with the tool sfdisk.
Easily create a partition table backup to copy to a new hard drive or just for a backup.
Use this only with MBR type of hard disks.
Save the partition table to a file.
# sfdisk -d /dev/sda > /root/sda.backup.txt
For recovery you can save this partition to a new hard drive with the exact same geometry.
# sfdisk /dev/sda < /root/sda.backup.txt
That’s it. After recovery you still need to format the partitions with the correct filesystems.
