If you really have 10TB of irreplaceable data, then at a minimum you should invest in another 10+ TB system for backup. And possibly a third, offsite.
In the more likely case that most of the 10TB data is replaceable, then I think the thing to do is to separate out the irreplaceable data, which can hopefully fit on a single HDD, and then get two HDDs, and backup to those in rotation, with one always kept offline and offsite or at least in a fireproof waterproof safe.
Is there any tutorial on how to backup/restore ZFS-snapshots using e.g. an external Harddisk?
2TB is about 500 DVDs. It takes about 30 minutes to rip a DVD. So 250 hours of labor. To recreate.
What about zfs snapshots and zfs send to another box?zfs snapshots aren't backups, they're pointers to existing data and copies of changed data.
there is no magic way to backup data when you're talking multiple terabytes and more. you either buy expensive tapes or you buy additional harddisks and keep them on a physically separate system and optionally a physically separate location.
Since most of my time is not spent at my computer, to get the ripping done requires I stop doing other work every so often. Making that other work much less efficient.Do you have to continuously stroke the DVD player while its ripping in order to get it to work? Otherwise, it should take about 1 minute of "labor" to rip a DVD, even if it takes 30 minutes for the rip to complete.

I might as well ask this since its a thread about storing massive amounts of data...
Does anyone know a backup service that provides sftp access at a reasonable amount?
heck, I'd be curious if anyone offers it at any cost. It seems like most folks want you to transfer using their proprietary software.

I'm surprised nobody uses my method among you guys. Be generous! Help other people (family is best!) set up their own servers, and "give" them your data! All the data that is personal or that you cannot give away like that, backup to online server somewhere else or take HDD copies off-site.

RaidZ-2 and snapshots DO solve a lot of problems in addition to this. For everything else (fires and theft) any backups MUST be off-site.
This has worked for me for years.
I forgot to mention that I do this as well. My friend and I tend to build similar setups year after year. With that, we've backed up each other's data in the past for an offsite copy.
The wife and I have been using crashplan for a while (free version). We are probably going to move to the "paid" version family plan soon enough because of how good this service/utility is. I mean $120/year for unlimited cloud storage for up to 10 machines = ROFL. If you go 4 years...$6/month...damn.

I am still making a push towards tape on critical data (photo's, work, etc)..but crash plan really takes need for duplication away from WHS and allows much cheaper "raid" setups. Right now going with onboard RAID5 with 4x3TB's HDD gets you a ton of space at reasonable performance.
