You need one copy somewhere else! What if there's a break-in or the roof leaks or whatever? My low-tech solution is two external drives, one of which is at my Mom's place and gets swapped every month or two.

Re: I Nearly Lost All of My Data
#42Here is what I do to hedge the risk of electrical failure (raid+usb on the same circuit), fire (both copies in same structure), malicious compromise of my machine and theft:
- My workstation has linux software raid-1 of 2x 6TiB drives (this provides robustness and uptime in case of single drive failures and ease of recovery).
- Another machine in my garage doing incremental daily backup pulls over the network. It is setup as multiple discrete hard drives thus partitioning single drive failures (low cost, the garage is a separate building, the host machine is an arm board that actually turns off HD PSU when not backing up, so hard drives are fairly isolated from power spikes).
- I make a monthly incremental backup (three sets) onto an external 6TB usb hard drive encrypted with luks. This drive spends 99% of it's life powered down in a cabinet at my office at work. It is protected against theft, fire, electrical spikes, etc... by my employer.
- The is not a *ucking cloud anywhere in this picture. I can get access to my backups within ~1hr in worst case (round trip drive to office to pickup my drive).
You Kids need to learn how to take care of your shit - now get off my lawn!!

#43I'm surprised it's not mentioned here but a lot of the Synology nas's have had power supply issues in addition to the prior Intel Atom issues. I swapped out four units twice each (1815+'s) and swore off their hardware permanently.
To be fair, at least with the Intel Atom C2000-series problem, I find it difficult to blame them. We had a network edge device from another vendor die due to the C2000 defect. I figure the best the vendor can do in that case is offer to replace/fix it, which the vendor in question did. Did Synology offer to fix their C2000 devices?

#44I had all of my backups on a 2TB external drive, which worked great until the MFT got corrupted somehow. Suddenly all my eggs in one backup basket felt a bit silly. Fortunately I was able to recover all of it. I'm in the process of partitioning out a new backup system to avoid that in the future.
Re: I Nearly Lost All of My Data
#45The best solution I found as an alternative to an off-site copy is to set up a USB drive and something like a Raspberry Pi in my car. When I pull into the garage, the house server senses it and syncs new data to it. This can be supplemented further by having it auto sync to a computer in your office whenever you pull into work. Add in some monitoring so you can get a phone alert if any of the synced copies are more t…
Does the RaspberryPi have enough CPU for disk encryption?
RaspberryPis can emulate Mario Kart on an N64, run Minecraft on Linux and even Mathematica at decent speeds; I'm willing to bet big bucks they can handle symmetric key encryption (which does not require much power).
If a crappy NAS can run disk encryption, so can a raspberry pi. They're deceivingly potent.
Re: I Nearly Lost All of My Data
#46There isn't really a good excuse not to have an offsite backup, especially when services like back blaze are $5 a month.
Also ... RAID is not a backup.
Re: I Nearly Lost All of My Data
#47> What are the chances of both a 4 disk RAID failing AND a USB drive at the same time?
Probably close to 100% if your house catches on fire.
Re: I Nearly Lost All of My Data
#48These kinds of scenarios are why I built Relica [1]. It backs up to local disks, network drives, remote computers (on LAN or anywhere with a public IP address), your own cloud storage, or our own special formula we call the Relica Cloud: one upload, five independent cloud providers -- replicated in real-time. And restores can use the open-source tool restic [2], so you don't have to be locked into Relica for accessin…
Can this also be used as a replacement for sync services such as Dropbox or SpiderOak ONE? In other words, can I sync accessible folders between computers in near-realtime, or is it only archival/backup storage?
No, Relica is not a sync service, because we do not want to sync your deletes -- we recommend using backup and sync together, because they serve two different functions.
Relica is archival software, but you can backup+archive your synced folders of course.

That’s on-site way too often for my tastes. If your house burns down while your car is in the garage, there’s a good chance you’ll lose the backup too. Adding a computer in your office fixes that, but why not just send your backups to it over the internet instead of using this ad-box vehicular transport protocol?

Does the RaspberryPi have enough CPU for disk encryption?
You can do encryption with any amount of CPU power, it’s just slower if you have less. Backups are not typically a case where speed is extremely important.
