dump/restore
Hi, I have a few questions about the dump utility. The info page says it works on the ext2 file system. Can it also work on the ext3 file system?
Also, if I have a CD-RW drive, can I back it up to a CD-RW drive like you can a tape drive such as: # dump -0 -uf /dev/cdrwdrive /dev/hda1 ? |
I think you need a prorgam like cdrecord to write to the CDRW drive.
|
dump -ua -f - /dev/blah | gzip -9 | cdrecord dev=0,0,0 speed=99 -
assuming it will fit. i haven't tested this either |
But can dump work on ext3? The info page says ext2
|
dump and restore are filesystem specific, so the real
answer is no, but since you can easily mount an ext3 as ext2 or convert ext2 to ext3, it might close to work. if you're lucky, it would work and might treat the journal as a normal file. If i were more bored now, i would try it for you, but you're on your own for now. i think there is a working dump and restore for xfs. |
