Ideal backup directory

henok — Mon, 15 Aug 2011 15:06:15 -0400

What is the ideal place for saving backups of code, websites, database, etc? /var/backups is reserved for backups of system files. I suppose one can create /var/backup but then users would have to be careful and pay attention to the distinction between backup and backups. Another possibility is to create a new partition and mount it at /backup, but that would be an over-kill. So, any other suggestions? Thanks.

rdiff - storing incremental data separately

mrahab — Wed, 09 Jun 2010 17:49:24 -0400

I am trying to develop a new backup scheme for our Linux servers using something based on rsync (rdiff-backup, duplicity). Basically, I would like to do full backups weekly on Saturday and daily incremental backups. After the full backup completes, I would like to take that drive offline and store it off site. Is there any way I can do this while still being able to do daily incremental backups? Is rsync the correct tool for this or would something else work better?

I tried to be as clear as possible, let me know if come more clarification would be helpful.

Looking for strategy on backing up data (linux folders/files)

Andy — Fri, 28 May 2010 15:00:38 -0400

I am looking to find a strategy for backing up data. I have an Ubuntu 10.04 box that I have essentially acting as a server. I work on multiple UNIX systems and I daily backup critical databases, directories, files, etc., via a combination of tar, bzip2, sshfs, and scp. Because of this, I have daily "snapshots" and this will begin to take it's toll on my storage space although I'm okay with snapshots but I was hoping to find out if there is a better way.

Any ideas or pointers are greatly appreciated. One item I am not familiar with and haven't studied is the idea of using tar, etc., to "sync" to an existing tar file. Maybe that's a better way so if anyone can point me in the right direction on that as well.

backup/restore third party ppa's

Troy — Sun, 16 May 2010 11:54:57 -0400

I use a couple of third party launchpad ppa repositories (mercurial, tortoisehg, medibuntu, etc.). I was wondering if there was a way (preferable a script) that would allow me to back up the ppa's and then later restore them? This would be very handy after a clean install of my system. Currently I can backup my package listing through synaptic but I can't restore it because I have to have the ppa's in place first.

Rsync backups using sudo instead of root

Sander Marechal — Sun, 09 May 2010 20:09:35 -0400

I'm having a little rsync problem. I am trying to move data from one server to the next using rsync. The data needs to retain file owner and permission settings. The files in question are not owned by me, but my account (on both servers) does have sudo access.

For example, I want to copy /var/www from server1 to server2. All files are owned by user www-data. My user account on both servers is sander and I have sudo rights on both servers.

server1$ sudo rsync -av /var/www/ sander@server2:/var/www

does not work, because sander@server2 cannot write to /var/www and cannot change the uid/gid to www-data.

server2$ sudo rsync -av sander@server1:/var/www/ /var/www

Does not work. sander@server1 cannot read /var/www.

How do I solve this?

Backup my Linux Box to a Windows Server

JC — Fri, 07 May 2010 12:51:54 -0400

I am new to Linux and I have read the post "which backup tool".

After looking at some of the suggestions in existing post, I can not seem to find something that does what I want to do, at least not easily. Someone told me there was a command line DOS type utility I could use but I haven't seen anything like that.

I have a Linux Server running:

Linux version 2.6.9-89.0.23.ELsmp (mockbuild@builder10.centos.org) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-11)) #1 SMP Wed Mar 17 06:55:21 EDT 2010

The Linux Box host vmware's Server which in turn host a virtual machine.

I need to backup the entire Linux Box to my Windows 2003 Server with the goal of being able to do a cold metal restore should the linux box fail. I am looking for something that I can schedule to do a full backup and has a restore utility built into it.

Thanks --JC

which backup tool ?

martvefun — Sat, 24 Apr 2010 08:39:20 -0400

Hello,

I'm looking for a backup tool on my (arch)linux.

On the archlinux wiki, I've found this list : backup programs. There is so many program I don't know which one choose and when I search review on the web I still found several others which looks great.

I'm looking for something to do incremental backup (save disk space and time), easy to recover and manipulate the backups. I'd like something easily customisable to do stuff (with bash script maybe) like "save my system every week, delete after two months", "save my home folder every day except the following folders, don't follow the links (to the partition or another) but keep them", "do incremental backup every x and a full backup every y", "save x every day, delete after after a week but keep one backup one week, two weeks, one month and three months old",...

I'm using only linux so I don't need a cross-system solution.

I tried rsync some times ago. It's a great tool but I had problems to keep the users and permissions. Also rsync doesn't allow to recover something else than the last backup (stop me if I'm wrong).

I heard a lot about rdiff-backup but never tried. Advantage to be able to recover previous backup.

In the wiki, there is link-backup. Never heard about it but it looks great, I may test it. Someone knows it ?

Unison : seen some good reviews. It has bidirectionnal synchronisation (feature, I don't really need).

rdup : another unknown program (based on hdup, like duplicity but looks more powerfull). I like the spirit of the program "not invent the wheel again and again" so instead of doing the backup, it uses another unix tool to do that. It can do compression and encryption. Problem, it copy the full file and not the difference (but if one backup fail, it's not so much a problem them). If someone has tested it, I'd really like to heard comments.

What do you use and why ? Thank you to develop your point and explain the main feature of the program compare to another.
