Re: Hot-backup a complete Debian install
first of all, sorry G i can't understand your point.
i can tell you about one of my experiences that can explain some points of
i had a machine with a scsi disk and linux installed, someday i started to
experience some i/o errors on that disk so i have to migrate the instalation.
so, i was looking for another scsi disk, but i only found an ide one.
the result was:
_ i backup the scsi partitions in the ide partitions (made by hand, equal or
greater size) with tar.
_ modified the fstab to match the root and the others new devices with mount
points.(/dev/sdax --> /dev/hdax)
_ update the bootloader and mbr!!
.. and voila! all in the last place before the errors...
it's not lvm but i hope some concepts helps you.
if the point is about file level backup tar (i think) is good.
a block level backup could be 'dd'
