But I suggest that 'x' needs to be quite large. Anyway I think we (or rather I) have done the subject to death, and it is time for me to keep quiet.

Yes, rsync is great for updating incremental changes but this is quite irrelevant to the OP's problem. For backup it seems this also somewhat reduces the effectiveness. For example when you are asked to recover the original of a file that was changed before the lastest backup. Many of us think it desirable to regularly archive complete backups.

Also using the "a" flag means the modification times are intact. I use rsync at work over 100s of systems and it is very effective, and the noc find it far easier to recover small numbers of files than having to go digging into dump files. The way we have got everything setup on a zfs backend mean we can do incremental forever, as well which is much more efficient than having to do regular level 0 dumps. > Malcolm Kay > > > I use it in our backup setup at work, and have restored > > countless freebsd boxes. > > > > When you repartition the drive remember to add the boot blocks > > > > eg > > > > fdisk -B ad0 > > bsdlabel -B ad0s1 > > ___ > > freebsd-questions@freebsd.org mailing list > > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > > To unsubscribe, send any mail to > > "freebsd-questions-unsubscr...@freebsd.org" > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to " > freebsd-questions-unsubscr...@freebsd.org" > ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Probably OK if you use snapshots. Leaves you in very similar situation as doing backups with tar. These schemes also alter the access times on files (which I guess doesn't usually matter too much). But dump/restore is no more complex to use than rsync and manages snapshots for you, so why mess about with questionable schemes.

The dump/restore should do the trick as long as you have another medium to store the dumps (such as another hard disk). You will store the images of your slices to the new medium using dump(8). You can then use FixIt console to re-partition and re-slice your hard disk and then restore(8) your images in the newly sliced hard disk. Actually, if you have another hard disk device, you can use piped dump/restore to copy the whole system from one disk to the other and make the second one your bootable disk. Of course you must have sliced the second device first. I've done this many times. The first was to remove an openSUSE partition I had, living in the same hard disk as my FreeBSD. The second time was to move my FreeBSD to another hard disk (physical device). The new disk became my boot disk. The third time was to move my system to another bigger hard disk device and at the same time be formated as ZFS. Now my system boots from this third hard disk device, having ZFS and the operating system is the same as that I first installed (of cource updated...)
