Sub_title: Use of dump command
 

Hi to you all,

I wish to back up and save an operating system I have installed on my hard drive to an external drive using the dump command, enlarge the partition on the hard drive, and using the restore command, restore to my new partition on the hard drive drive.

Is this possible using Puppy?

Pudd is offered as an alternative but would result in my external drive being overwritten as it makes use of the dd command.

Or am I on the wrong track again?

All words of wisdom gratefully received. Thank you.

It may be helpful to post specifics as to the OS or at least the filesystem that is being backed up.

For Windows NTFS I have used the program ntfsclone and for Ext2/Ext4 I have simply used mksquashfs (unsquashfs to restore after re-creating the filesystem with mke2fs). However you have to be fairly comfortable with the command line to attempt this kind of solution. Also, from experience the best laid plans dont always work. I have restored Windows with NTFS partition about 3 times now with ntfsclone, ntfsclone seems to work nicely but on one occasion the system wouldnt boot without having to run the Windows disk repair utility, wasnt sure why but with anti piracy security systems even an exact filesystem backup may not always work. There are boot sectors etc that may also have to be dealt with.

With Ext2/Ext4 Puppy linux I have used the very useful gparted utility which comes with what I believe to be nearly every version of Puppy which can be used (with a Puppy live CD or DVD , pfix=ram) to resize an existing ext2/4 partition though again it is important to have one preferably two or more backups of the system on USB drives etc.

I would avoid using dump as it can be buggy -and should definitely not be used to dump from a mounted partition.
