I can't afford 10 more terabytes of space to create a backup right now. Guess I'll just pick 50gb of non video content to back up.

Also what is the basis for the claim that 33% of people have never backed up anything? It seems like it would be far higher than that, but I'm not really sure what they consider having done a backup. Copying a picture off your camera to your computer might be considered a backup to them.

Funny timing. Had a near-panic last night where I almost had to tell my wife I lost the last 2 years worth of photos because backups are stale. Fortunately, they were all found on an old laptop, so disaster averted. I spent last night looking into off-site backup solutions, and haven't yet found one I would be willing to pay for. They all seem to require strange client software to work. Is there anything out there wh…

Not sure if you consider Tarsnap to be a "strange client"

My personal backup plan for family photos and non-work stuff:

Keep 2 copies on 2 external HD's. 1 gets backed up twice a year and put into a safe deposit box at the bank. One gets backed up once a month and put stored in filing cabinet in our house. I will also make backups onto DVD occasionally.

In addition to these local backups, I run a daily job to backup to an FTP & dropbox.

A friendly reminder to everyone. RAID is not backup: http://serverfault.com/questions/2888/why-is-raid-not-a-back... For your home, consider an offline service such automatically backing up to a NAS as well as an online service such as Crashplan or Backblaze.

Has anyone created a backup app that interfaces with glacier?

Does anyone have an open implementation of the glacier api? I'd like to add support for it to my backup tool, but I don't want to have to take on the financial risk of a large bill from Amazon if I happen to mis-use the api. So I'd like to try it out on a local server first, to project what the cost would be after a few months of use.

I wish that they included options for Linux too. What Linux backup tools do people use? Currently I'm making do with a bash script that's just a wrapper around rsync, but it'd be nice to have something a little more powerful, especially with the option to back up things to glacier, etc.

rsync.net lets you do things like this:

  mysqldump -u mysql db | ssh 1234@usw-s001.rsync.net \ 
"dd of=db_dump"

and this:

  ssh user@rsync.net s3cmd get s3://rsynctest/mscdex.exe
and this:

  ssh user@rsync.net "git clone git://github.com/freebsd/freebsd.git freebsd"
... and has had a "HN readers" discount for new users for many years now.

Not to mention, "29% of all disasters are caused by accidents". What on earth are the rest caused by? I'm sure a few are caused by malice, but I strongly doubt that it's 61%.

Earlier quoted context omitted.

Do you do anything to check against corruption (e.g. bit flipping)? I've been experimenting with md5deep recently to accomplish this, but it's a little time-consuming. I'd be very interested in hearing about more efficient ways of dealing with this problem.

No, except daily snapshots. If I would find main version corrupted I can always recover old version a few month back. I I found bit flipping problematic only when transferring larger amount of data over network.

If you are not checking it, how do you know your drives are not flipping bits?

rsnapshot (http://www.rsnapshot.org/) which is a wrapper around rsync.

Backups go to a local machine with a three drive linux software raid-5 array.

Occasional offsite sync to another remote Linux box.

I use tarsnap for all my backups, but that's a service as well as a tool. This is my daily crontab: http://pastie.org/8982530

Same here. Just did a full backup of my VPS: Total size Compressed size All archives 3.7 GB 1.5 GB Deduplication ftw.

That's just showing the compression (deflate). Deduplication is why "(unique data)" line which you didn't paste will be lower.

I had a conversation the other day with a bunch of wedding photographers and it’s amazing how much money they spend on a yearly basis on backup. They all shoot raw and they end up with something like 50-60GB of data per event. And that’s only for photographers, videographers are on a completely different scale.

Now, their number one problem isn’t storage per se, since cost per TB is constantly dropping, but uploading data to the cloud. It takes them anything from days to a full week to upload data.

So here’s my $64.000 question. Why hasn’t anyone tried to disrupt this industry? How about setting up a cloud backup company that sends you a portable disk where you write your data and then send it back. From my understanding money isn’t an issue, they would gladly pay tens of dollars on a monthly fee if someone could handle all their backup issues for them.
