What do you folks out there use for backing up your systems under linux? I've been using tar lately but I notice that for very large archives, tar is EXTREMELY slow! It's taking me over an hour to extract a single file from a 20GB archive. There's got to be a faster and better way to do this. I didn't think it took terribly long to back the stuff up but extraction takes forever. Is cpio better for this perhaps? I thought about zip but I understood there were problems using zip/unzip for backups; besides, I think there's a 4GB limit on zips; I could be wrong there. I've heard about amanda but that might be overkill for my residential setup with 3 computers.

I have had great success with rdiff-backup -- it does not compress except for the differences, but the nice thing is that if you want to restore the current version, you can just copy, otherwise restore of past versions is quite fast. Disk space is cheap, so this s a great solution for me. on Wednesday 10/29/2008 Steve Holmes(steve@holmesgrown.com) wrote > -----BEGIN PGP SIGNED MESSAGE----- > Hash: RIPEMD160 > > This assumes you backup your stuff at all:).

Hi, For backups, I use rsync. I know there are other solutions that use rsync in various ways, but I just use plain old rsync by itself. As was pointed out here, it doesn't store backups in a compressed form, but to me that's a convenience. It can compress when copying over the network but for a LAN, I don't worry about it. I was recently moving my files from a Windows file server to a new Linux install. All I had to do was this from the Windows side: c: cd\ rsync -av * files@fileserver:c To backup remotely, such as from the office Linux server to home, I do something like this: rsync -av tony@example.com:. . I probably don't need the dots, but I put them in just in case. The -a switch stands for archive, the -v for verbose. After a while, you won't need the -v switch, but I find it useful to get an idea of its progress and to let me know how much data it transferred. The -a tells it to preserve owner, permissions, date and time, etc. Otherwise the files will have the current date which I don't like. As always, read the rsync man page which includes lots of examples or look at the help which you get with no arguments. It's of course available on Debian, Cygwin, Gentoo and BSD. On Debian, do "aptitude -q install rsync" and experiment away. Another backup solution I use is not free but is the best I've found for imaging. That is Image for DOS or Windows. There is also an Image for Linux but I've not tried it. I suggest Image for DOS which you can run from a boot floppy. It will backup Linux, even though it runs in DOS. It compresses everything and is good for more permanent backups that you would set aside or put in storage. Go to: http://www.bootitng.com/ Again, it is not free and you have to actually buy the software, but I really haven't found anything that is free and works as well. You could try partimage though but I know nothing about it. ^ permalink raw reply [flat|nested] 4+ messages in thread

Referring to your usage of rsync under Windows; be aware of the following: NTFS stores different time stamps with different precision than those stored under Linux, not all these attributes will be retained. Also rsync will not store or restore nt acls if your storage network share is samba without special support on the Linux side. the above is not important if it is only the files you wish to preserve.
