Re: [expert] clonning HD
Maybe it's now solved, but just in case... I got my backup/recovery solved by: * Making the backup file: find /directory_to_start_backup_from -xdev | grep -v "/path_not_to_backup/" | cpio -o -H crc | bzip2 -9 -k > compressed_backup_file.cpio.bz2 * Restoring backup (to current directory): bunzip2 -kc compressed_backup_file.cpio.bz2 | cpio -idmu --no-absolute-filenames * Listing files in backup file: bunzip2 -kc compressed_backup_file.cpio.bz2 | cpio -itv You can use split to write to CDROM if back_file is too big (for a 80min CD): split -b 68000 compressed_backup_file.cpio.bz2 And getting then back is as easy as: cat file1 file2 ... fileN > compressed_backup_file.cpio.bz2 Also incremental backup is easy this way: 1) Do touch /path_to_file/date_from_last_backup when you do a backup 2) To do the incremental one just do: find /directory_to_start_backup_from -newer /path_to_file/date_from_last_backup -xdev | grep -v "/path_not_to_backup/" | cpio -o -H crc | bzip2 -9 -k > compressed_backup_file.cpio.bz2 Long commands but easy (I think ;-)) Good luck!!

Note that dump simply won't work reliably at all even in 2.4.x: the buffer cache and the page cache (where all the actual data is) are not coherent. This is only going to get even worse in 2.5.x, when the directories are moved into the page cache as well. So anybody who depends on "dump" getting backups right is already playing Russian roulette with their backups. It's not at all guaranteed to get the right results - you may end up having stale data in the buffer cache that ends up being "backed up". Dump was a stupid program in the first place.

Right now, the cpio/tar/xxx solutions are definitely the best ones, and will work on multiple filesystems (another limitation of "dump"). Whatever problems they have, they are still better than the _guaranteed_(*) data corruptions of "dump". However, it may be that in the long run it would be advantageous to have a "filesystem maintenance interface" for doing things like backups and defragmentation..

RE: [expert] clonning HD
Thats an interesting point... I have a spare 8 gig hard disk here.. I was toying with the idea of setting it up with all the packages and settings I use accross our network.. as an example: ext3 all round. postfix=>amavis-new=>spamassasin/Trend filescan and the dozens of modules compiled to get it all working. it takes ages to set this all up over and over again.. would be great if I had the base install on my 8gig drive, and could use something to mirror it over to another drive.. I don't care about the partition size, I could resize them myself easily enough if I need to. I just get sick of setting up the same type of box's over and over again... One of these days I will play with making my own rpms.. so I could just install them all in one hit.. but right now I don't have time to do that.. (incidently, how hard would it be to make a single rpm that would install all my spamassasin/amavis-new/filescan stuff???) I only know perl and the basics of ansi c++, so I don't know if I have the required knowledge to do it. any tips? rgds Frank -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Alan Wilter Sousa da Silva Sent: Friday, 13 December 2002 9:02 PM To: [EMAIL PROTECTED] Subject: RE: [expert] clonning HD Thank you Peter, However, with dump/restore I couldn't change my filesystem from ext2 to reiserfs, could I?

RE: [expert] clonning HD
Hi Alan dd will only copy block for block normally, so if you are copying from a 40Gb disk to an 80Gb, the resulting filesystem will still only be 40Gb. Much better to use dump/restore etc and reinstall LILO etc to transfer it. The other benefit dump/restore is each file is treated as such, rather than just a bunch of disk blocks which is a good check that the filesystem consistency is good. If you just want to clone same size disk to disk then you can use dd as a short cut, but if you have time go the dump route. Just my 2p worth, but has worked for me over many years.
