Encrypted Snapshotted Remote Backup

I just read about Colin Percival's idea for an encrypted snapshotted remote backup service.

Please read his post for more information. Colin would like to know if you would find such a service useful. He appreciates any feedback you send, and since he reads this blog he will see comments posted here. Thank you.

Colin,

I'd definitely be interested in this for some small business clients of mine that are looking to purchase backup systems. I'd use it myself. By cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 way, I know you're a FreeBSD guy, but you might want to take a look at Sun's X4500 (aka Thumper) for storing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 data. 24TB in one box!

Is he familiar with BoxBackup? http://www.fluffy.co.uk/boxbackup/ is an open source tool to have versioned remote incremental encrypted backup tool.

For Windows users, a service from Mozy.com, is doing encrypted off-site backups. I use it personally and think is great. I even paid cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 annual fee for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 full 30GB service.

If I cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y had a Linux client, I would use it as well.

I thought I was cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 only one who ever thought of this and cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365n I found duplicity.

It is also in cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 ports collection as sysutils/duplicity.

Thanks to all cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 people who have offered suggestions; and thanks, Richard, for directing people to my post. Unfortunately none of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 suggestions offered are adequate to my needs; see http://www.daemonology.net/blog/2006-09-14-more-about-backup.html for details.

If you are narrowly focusing on FreeBSD, you are likely to find a niche that you can satisfy technically, but I would question its commercial viability. IronMountain bought cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 LiveVault service a few years back and have thrown resources towards it. PC coverage starts at $15/mo for unlimited data storage. Server provides cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 ability to backup open files and databases on Linux, Solaris and MS servers.

None of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 existing backup solutions seem to fit cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 criteria that Colin has set. So yes, I'd love to see this implemented.

I was running rdiff-backup (cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 non-encrypted version of duplicity) for a while but was scared off by cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 use of Python "pickle" format data files. Too often I ended up trashing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 entire backup archive containing snapshots going back in time and starting again with a full backup.

I am in complete agreement with Tim Bray that cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 backup solution must use no proprietary (or undocumented) formats. In ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r words, use tar and bzip2 unless cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365re is a really good reason not to.

My current solution is a set of scripts to tar and bzip, followed by manual intervention (bad I know) to encrypt using GnuPG and upload to Amazon S3. I would very much like to see a cross-platform and well-maintained script to do this automatically.

BTW Amazon S3 is by far and away cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 best off-site backup destination for me. Thanks to S3 I'll never have to deal with crappy unreliable tapes ever again.

I think this is why cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 project should be open source (BSD licensed). Folks make money off supporting open source version control, security monitoring, operating systems (in NAS various embedded devices etc.) and ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r network infrastructure type apps despite cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 existence of commercial equivalents. Mostly becaseu some orgs *must* host cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir own stuff. There's no reason why someone like Colin couldn't offer cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 service *and* sell his skills to cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 highest bidder.

The question is can he code up this cool application in his spare time? Maybe if some financial collaborators could come up with sufficient money to support him for a long enough time while he worked on it we could make cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 "encrypted backup" equivalent of apache available to cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 world.
