hi all,
I use rsync to copy/backup ALL my stuff to another disk.
IMHO, rsync is overkill here. I would:
mount /dev/sdc1 /mnt/backup; mkdir /mnt/backup/month.day.year cd /home;find . | cpio -vdump /mnt/backup/mon.day.year
how about cp -a ?
How about "find -newer" to just back up things that have been added or changed? A big space saver. *However*, this leaves things deleted since the previous backup(s) in the previous archives. A *good* or *bad* thing? Depends on what you want to achieve.
Rsync can handle that situation for you, and so is better if you don't want to keep deleted files around.
The cpio solution offers a lot, most beneficial here is the ability to bzip the archive (anticipating it won't be frequently used), saving a lot of space.
As long as the majority of the files are not plain text - I have had really bad results using bzip2 on text files - specifically, massive file corruption. I have had to go back to pre-bzipped archives to rebuild these files - not a fun task.
I'd go with cpio if rsync causes problems. YMMV.
