I cannot move it back to the same title without admin intervention. They have to delete the redirect first. Sorry for changing the name in the first place; I didn't realize subsections worked only for user pages. pwd 13:27, 23 December 2009 (EST)
- Oops! Sorry; didn't realize that was the cause of the hold-up. I've removed the redirect. -- pointone 13:34, 23 December 2009 (EST)
- Moved the page even though I don't like the title. I really don't think the naming scheme suits it; should be Full system backup with rsync, in my opinion. pwd 14:10, 23 December 2009 (EST)
Thanks! Neat method for a sync-type backup! The only question I have is what happens if you
dd the boot sector (first 512 bytes) instead of running GRUB? --VitaminJ 22:18, 11 November 2009 (EST)
I don't know if it works with
dd, since the partitioning scheme can be different on the two harddrives.
- I vote for merging this with rsync.
- I second the vote.
Yep, I think you are right, I think that GRUB hardcodes the path to menu.lst in the GRUB boot program, so if you change around disks it won't work.
As an alternative, an article on using tar instead might be useful because rsync may improperly preserves permissions across filesystems. For example if you backup from ext3 to XFS, and try to restore back to ext3.
- The only issue would be doing it with FAT or NTFS were permissions just aren't possible. Coincidentially, I've done this exact setup using XFS and ext4 wihout anything breaking down. I only had problems between reiserfs and *, but that was due to SELinux context. Dres 21:22, 18 January 2010 (EST)
I think its a good idea to mention dirvish here. --Moere 03:37, 1 March 2010 (EST)
on the same topic, you can also look at a free script that i wrote to backup the whole disk with rsync here: http://blog.pointsoftware.ch/index.php/howto-local-and-remote-snapshot-backup-using-rsync-with-hard-links/
It uses file deduplication thanks to hard-links, uses also MD5 integrity signature, 'chattr' protection, filter rules, disk quota, retention policy with exponential distribution (backups rotation while saving more recent backups than older). It was already used in Disaster Recovery Plans for banking companies, in order to replicate datacenters, using only little network bandwidth and transport encryption tunnel.
Can be used locally on each servers or via network on a central remote backup server. windows server could also be backuped by using a linux box that mount smb shares from them.
I'm getting the following error with this script, unless I use --delete-excluded, although that was declared unnecessary:
cannot delete non-empty directory: lib could not make way for new symlink: lib cannot delete non-empty directory: lib64 could not make way for new symlink: lib64
- Rsync doesn't delete... You must have modified the script? --DSpider (talk) 06:10, 8 September 2012 (UTC)
- I had the same problem, turned out that I had forgotten that the script needs to be called with a destination argument. It doesn't check for this situation and will use an empty $1, which causes it to be ignored and it'll try make a backup to your root directory.. very scary! I've now added a check to the script to prevent accidental misuse. Timusan (talk)
Why the -H option is not added? I've done a quick search in my arch system and there are a lot of hard link in the /usr/share folders. Moreover should the -delet option be added to in order to be sure that the cloned system contains all and only the files which are present in the original one? Thank you, Xwang
What happened to this page?
Ok, I started this page, so I'm biased. It used to be clearly written, with an easy to understand example on how to use rsync and its exclude format. Now it's a one liner with the excludes mashed together and most of the page is dedicated to setting up your fstab. Why? Wooptoo (talk) 19:47, 6 March 2013 (UTC)
