Ask Slashdot: Open Source Back-Up Tool For Business? 118

New submitter xerkot writes: I am looking for a tool to make backups of PCs in a big company. We want to replace the one that we are using at this moment for this new one. The tool will be used to do backups of PCs (mainly Windows, and a few Linux), and we want to manage these backups centrally from a console, being able to automatize the backup process. The servers of the company are backed up with another tool, so they are out of scope. In the company we are being encouraged more and more to use open source software, so I would like to ask you, what are best open source tools to do backups of PCs? Are they mature enough for a big company?

    What exactly are you backing up? Entire disk images? Or just user files?

    If disk images, then something like clonezilla, perhaps set up to boot from a TFTP server. Boot the machine via WOL, kick off the TFTP, automatically dump the image out to a server using the machine name or MAC address or something as a unique identifier

    For user files only (ie, My Documents or whatever) can you set up network based home directories ? And then just back up the server they live on.

      Agree, in my experience Clonezilla [] does as well in this arena as the commercial offerings. Be wary, however. All of these products can behave a little funny sometimes in certain environments. Whatever you choose, test it out all the way through a backup and recovery before relying on it.
    • For user files only (ie, My Documents or whatever) can you set up network based home directories ? And then just back up the server they live on.

      If you do this, you better have an insanely reliable network with at least gigabit speeds. Where I work we have all of our *nix boxes set up with the user home directories on NFS and when the network goes out, we have a lot of employees who can't do their jobs. Even a few hours of outage can be extremely costly. On top of that, no one who works with large files uses their home directory for anything due to the limited space and slow (100Mbps) network speeds. Instead everything is stored locally and back

      • Yes, but once you have a Windows network to the point where anyone can sit down at any workstation, with all user data being stored on a file-server, you no longer have to back-up the user workstations. I managed several networks of between 50 and 200 workstations, each with a single Samba-based DC and file-server that was backed up off-site via rsnapshot. The workstations were imaged via FOG. Once we had a working image for a workstation (which could take a couple of days to prepare from scratch), the bot

      You don't want to do that, you only think you do. That needlessly creates a security problem by intentionally installing a remote control vector. What you want is a central notification system so that if a machine expected to back up does not, you find out about it and can send on the IT staff.

      What i.r.id10t alludes to is also correct: figuring out how you can restore a machine to operation is step one. That determines what form the backups can be stored in which, in turn, determines what backup tools you c

      Amanda is great if you're backing up only Linux clents, but the Windows Amanda client is a total abomination. Not been updated in over 2 years (don't believe the version numbering - check the timestamp of setup.exe), pointlessly uses a MySQL DB on the client side (ridiculous!) which the Linux client *or* server doesn't use, regularly times out, regularly crashes, produces byzantine error codes without any description/documentation of them, much slower than the equivalent Linux client and produces ZIP64 backups that are pretty well impossible to extract from on Linux (which is annoying, because the Amanda server side is Linux-only).

      We have a Ultrium tape drives with multi-slot autoloaders/barcodes, so there are very few Open Source backup solutions that can handle this (including tape-spanning if needed) out-of-the-box. Bacula was another potential solution, but it's horrific to set up (makes the dreadful Oracle DB install process look like a breeze) - just reading the Bacula install docs brings me out in a cold sweat :-) I guess business-level backups just aren't sexy enough to warrant a decent Open Source solution...

    I once was in a crossroads of choosing between stuff like Clonezilla and Bacula, for small business purposes. Bottom line is they add a lot of complexity for low to no flexibility. I ended up building my own tar/move/ script with cron triggers at after ours downtime, then I would simply move them around network locations for avoiding single points of failure messing up the backups. Adding your own exceptions for the backup is a plus. At the last point, I had something reliable, fast, and that would require the simple overhead of re-installing Debian before the actual restore, then an update-grub and a change in fstab for the new disk replacing the broken one's UUID (because you don't really do that many restores so it's a fair trade-off, while you do save time exponentially by not backing up the entire OS).

      Bacula is highly, higly customizable: for example, I wrote a program in shell which connected Bacula with Oracle RMAN, and now Bacula obs kick off RMAN database backups every day, then syphon the RMAN backups off to tape. And Bacula controls the tape library and the barcode reader through other external programs. Such a thing would not be possible were Bacula not designed to be so flexible as to interface with everything and anything, including emulating virtual tapes as entire

        For instance, you argument for customization with an example based on the trigger of a proprietary recovery system. So you can trigger a remote process with Bacula. I have a one-liner shell script command for that, nice job. Especially with a proprietary system which the OP specifically excluded in the title (Open. Source.). And from the clues I got, Bacula

    I use Bacula for my home computer; it feels powerful enough for a small office, and is very versatile.

    It has three main components: a client daemon that you install on the computers you want to back up, a storage daemon that you install on the computer that will write the backup files and/or tapes, and a director daemon which controls the backups. The director and storage daemons only run on unix-like operating systems (BSD, Linux, Solaris) but the client daemon has also been built for MS-Windows. []

      I regularly use Bacula to back up a network of about 20 workstations and a couple of servers, plus a remote one (connected through a VPN). It's fast and reliable, if I really have to nitpick there are some quirks, though they depend mostly on lack of disk space for the backups (this is a non-profit with a tight budget) and lack of time on my side for fine-tuning the configuration. I'm really satisfied, since 2008 Bacula has saved our ass a number of times with minimal effort and maintenance.

    I worked at a scientific institute, and they simply installed OwnCloud everywhere. It's got a client for most platforms, syncs to a server, and allows you to back up the server in the usual fashion.

    It worked so well, that when I started doing consulting (at the client site), I got my own VPS with Debian, and installed OwnCloud server on that. Then installed the client on my private laptop and the laptop that I got from the client. Works beautifully, because communication is over HTTPS. Company firewalls don't block that. I tried other things like BitTorrent Sync, but these use special ports.

    Set up home drives on file servers and back those up. Teach users that those are the only locations that are backed up. Set up the PCs to use that as the default home location. You can do this on Windows and Linux just fine. Invest in the server -- redundant power supplies, RAID arrays, failover, etc. You could even look at various open source NAS devices, or whatever works for your environment.


    Backing up user PCs doesn't scale well and becomes a thankless task for some poor employee who has to keep up with broken backup clients. It's far easier to scale when you only have to keep up with the file servers. You have some number of clients saving to each server, but that's that number of backup clients you don't need to deal with. This frees up IT staff for other, more useful tasks.

    It also allows you to replace end-user PCs with a simple re-image rather than trying to recover or fix anything. End-user calls and says their PC is going whacko, you pull a spare off the shelf and lay down a fresh install. Show up, take the malfunctioning equipment away and diagnose it on your time, while they get back to work. Since all the files are on the server they can just get back to it rather than waiting on you to try and fix whatever might be going wrong.

      I agree with this but I can't tell you the number of times, even where reasonably well implemented, it resulted in A User of Some Organizational Clout losing some data they wasn't saved where it belonged. Mostly this was ultimately consequence free, but getting to that state often required some kind of extensive recovery.

  • Rsync is simple, lightweight, has been around forever, and gives you incredible power. Assuming by "manage centrally from a console" you mean that you have remote admin access to all the computers in the scope, it's as simple as a cron job running your Rsync script. You can trivially make several versions for different use cases (Linux vs. PC) and only have to configure the setup once in the cron job. After that, you only need to touch it if you make changes.

        Backuppc is exceptional for linux, but for windows and the infamous pst files, better to have a client/server architecture of the BURP software.

  • The first thing I have to say to everyone who asks me to design a backup solution is "what's your recovery solution? what are your recovery needs?". Then design your backups around that. Don't back up anything that won't be restored. You have to protect against both disaster recovery (loss of total system) and operational recovery (file deletion, corruption, historical trails). DR for a PC is usually from a stock image; OR for a PC can be managed through much better methods than PC backup.
