How do you back-up?

I have a script that backs up my Subversion repository every day, to a second drive on the server. Once a week it also makes a copy to a zip drive (250 meg). Every once and a while I manually use Sync Toy to back up the primary server drive to a second one. Nothing important is stored locally. :)
And if the building were to burn down? What then? If you don't take a backup offsite you're flirting with disaster. I used to be a network tech and you'd be surprised how often buildings burn down or computers get stolen or some other disaster in waiting. If you don't separate your backup from the computers your backing up you only have half a backup.

I use CVS on my server, located 2000 miles away in Texas. Once up there, I then keep both my dev systems updated. So, if I lose one dev system (which as happened), I can continue with the other. If the house burns down and I lose both, I have a remote backup. If a nuclear war wipes out the entire country, well then, who cares, right? Marc Pensieve

The source code is backed up to the source-control system across the network, to a server a few buildings away. the source-code and most work areas are copied to my home system as a backup, backed up on USB disk at work, and backed up on USB disk at home. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

Ah the only decent backup anyone mentioned. If it's not backed up or taken physically out of the building where the computers are it's a disaster waiting to happen. I used to do network computer service for many different companies and it's surprising how many people would backup and leave the tapes sitting in a box beside the server. We had a few fires to deal with and luckily when we took charge of a network we enforced the offsite backup rule and in one case got an entire law firm up and running over a weekend in a new building with new computers a month after we had gone in and cleaned up their network and insisted they take the tapes offsite. We looked like geniuses to them when the fire happened a month later and they realized the implications of their old backup system.

What we are using in our enterprise is an AIT drive. it is installed in our server and makes a copy of everything for what is has been programmed. We have it installed in a linux server so the program we are using is completely free and moreover the tapes that this system use are very reliable, we have been using them for two years and it is working as the first day. Of course there are lots of software solutions in order to make the backups with those drives, but that one is the cheapest. Our drive can backup 73 gb's without compressing but there are lots of available different capacities. The only thing that is a little bit annoying is that when you must recover something, it can take only 10 seconds or it can take even 4 hours... well after all it is a tape... you can find more information here: http://sony.storagesupport.com/ait/windriver_2k.htm[^] Of course this is not the best solution, but it works well for us. Best regards.

That's not a backup at all, just a copy. You must take your data offsite in case the building burns down right?

I take my CD's that I copy my files to and move them to my parents house near Disneyland since I live in a high fire risk area. I also have a Linux box that I drag-n-drop stuff with ssh. Paul

VSS has the option of compacting the database for backup purpose.

i use Retrospect and an external 200G USB drive to do automatic incremental backups twice a week. then once a month i do a full backup to DVD using Nero. Cleek | Image Toolkits | Thumbnail maker

Don't forget redundant backups. Many people reuse media for so long it becomes unreliable, but they have no media rotation, no redundancy, so even if they follow the idea of taking it offsite, when it comes to disaster recover the first comment usually goes, "what do you mean you can't read the backup tape?" NASA does triple redundancy and single component failure is actually fairly common, double component failure less common, and triple rare. You can never prepare for "everything" but taking reasonable advantage of oportunities for redundancy is just smart. If you have a telecommuting policy in place (or "work at home" set of rules), such that an employee can work from home on rare occasions... ask them to keep a copy of all their work at home if the work isn't classified. Now you have instant offsite backup. :) It is important to think of backup recover as a "when" not an "if". It may never happen, but if you prepare with the idea that the building will burn down, where do I put my backups?... you are already on the right track. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

Yes of course, standard 10 tape rotation (monday, tuesday, wednesday, thursday, friday1, friday2, friday3, month 1, month2, month 3 + plus some sort of year end burn to optical storage) with test restores. I've seen every possible way data can be lost in my years doing onsite network tech support and it's easy to avoid them all with a little forethought. The truly scary part is knowing first hand how many banks, professionals of all kinds, health institutions etc do not do proper backups. We enforced good backups at so many places that had little or no backup protection when we were first called in over the years, places that the general public would just take for granted wouldn't lose their data.

[Knock on wood] mine works pretty well, had I known about all the troubles people had with them when I bought it I wouldn’t have. Getting an external drive is on my list of things to get. I may end up taking the cheap route and just get a drive enclosure and put one the now extra internal drives I have laying around in it.

Don't knock the inexpensive route! We have upgraded the disks twice in one of our external USB/firewire enclosures, and I am waiting on another for a 500gig drive for another team. Having an external, and upgradable, replaceable solution is a really, REALLY good thing. You can start with one of the drives laying around, and upgrade later, as needed. Just one word of caution.... your drives will last MUCH longer in a case with a fan. Air flow out of the case is much more important than pinching the drive with aluminum and expecting the room air to keep it cool. And they are only $10+ more expensive... why anyone would skimp over $10-$20 I don't know.... _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

Yeah I know.... back when I worked a one-man-shop as programmer (I handled all DP design/builds accounting-related) I had a good peer-relationship with the DP manager at one of the local banks. We were comparing backups because I just implimented an off-site backup for work. He said that was much more difficult for banks, you can't just hand off that data to someone else. I looked at him with an odd expression... and said, "you have 12 branches around town right?" he agreed with a puzzled look. "8 of those have safes with keyed safety deposit boxes in them right?" and a lot more hesitantly he agreed.... Why don't you put your tapes in one or more of the other safes around town, the loss of one or two safe-deposit boxes for customer use is a lot less concern than going without offsite backup. Either that or on your secure network when you pull the download batches from the branches, upload a backup. I think he did the latter within a few months. Dangit, you have a secure network and trusted computers on the other end, use it! _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

How do I back-up? 1. I don't back-up. Back-ups are for girly-men. 2. I put the shifter in reverse, check the rear-view, and hit the gas. 3. Using the moonwalk. 4. By eating too much cheese. 5. I back up my computers on CD. I've thought about trying out USB flash drives but haven't followed thru yet.

Yea know, that's a really good point.

Yea, I had planned on getting on with a fan regardless. Have any experience with network based, storage devices? I have seen a few that aren’t much more than an enclosure running Linux and samba. Thanks for the advice…

I just recommended one for my parents. They want to have the same backup for three machines (two desktops, one laptop), they have a network, it is the one that makes the most sense. I don't have any experience with any per se, we now own two at work, but they are not the enclosure kind -- somewhat larger scale. :) _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

Sheesh, I'm period enough (even though it may not sound like), don’t add to it. :) I start a new job here in about 2 weeks, won’t be doing any coding for them. If my employer really cared they would provide a solution. Might not be a bad idea to at least look into pushing the current day to my google email that would be a cheap alternative for offsite backups.

It would be nice just in that I can put it anywhere. There is enough junk plunged into the server already don’t need to add one more device.

Back up every single day.... I use Genie Backup[^].. I backup to an external USB drive, I also make a hard CD backup 1ce a month or so. I Back up \inetpub as well as VS 2003 & 2005 project directories... Matthew Hazlett Sometimes I miss the simpler DOS days of Borland Turbo Pascal (but not very often).
