And certainly, not all of the models are going to be ones that you will typically use in your computers. Ok, so Backblaze has a freaking ton of hard drives. This leaves us with 71,939 production hard drives. For our evaluation we remove from consideration those drives which were used for testing purposes and those drive models for which we did not have at least 45 drives. Of that number, there were 1,553 boot drives and 72,100 data drives…Īt the end of Q4 2016 Backblaze was monitoring 72,100 data drives. At the end of 2016 we had 73,653 spinning hard drives. Their methodology is:īackblaze has recorded and saved daily hard drive statistics from the drives in our data centers since April 2013. Well, we think so, and apparently so does, as they actually have a hard drive failure rate study up on their website. But what about the idea of avoiding risk by finding out which manufacturers tend to sell the drives that fail the most? I mean, if you had some way of tracking which hard drive companies you should avoid and which ones you should buy from, wouldn’t it make the whole data safety concept a whole lot better? This is what backups are for, of course, and certainly doing that is going to ensure that there’s practically no way you have to require a data recovery company like Hard Drive Recovery Group or our services. I do not consider DEVONthink’s sync as backup.It’s basically a fact that when it comes to hard drives, whether they are old platter and spindle style or brand new SSD style, you’re best to not trust them on their own. Synology Backup files I look at log to make sure they happen. I test restores from TimeMachine at least a couple times a month if only because I want to restore back to a previous version of a file I am working on. : Synology NAS backed up daily to an attached USB drive and Backblaze B2 sync. Use standard IOS backup to Apple iCloud entire device. Syncs with iMac (Bonjour, WebDAV, and CloudKit). Syncs with the iMac (Bonjour, WebDAV, and one small database using CloudKit) Same as above but no Backblaze or Zip file export. I keep a monthly copy of these zip files for a few years. Also, like you have a scheduled (with cron) AppleScript to do an export to Zip of the DEVONthink files once a week (those zip files captured in the regular backups). Backblaze also running taking all it can to provide remote copies. Also running Synology Backup on selected key folders, including DEVONthink’s. : iMac has Time Machine running continuously to a Synology NAS server, and two a connected USB drives. (not a direct answer to your question, but wanted to share how I do this) I’m not a fan of encrypted zip archives for anything bigger than 5 GB. Where do you store your exports? If it’s on an external drive, you could create an encrypted APFS container as an alternative to the above mentioned options (HFS+ volumes can’t be encrypted any longer after Catalina). I don’t see the value of doing extra exports in that case. It can also search within databases and since I set it to run every 30 minutes, it’s a bit like version control. Arq works well too and preserves metadata (which can be an issue with other backup apps like Backblaze ). You can also browse or search the contents of database backups easily in Finder (show package contents) or something like Backup Loupe (or even DEVON’s EasyFind) if you only need to get to specific files. I’ve restored databases with Time Machine in the past without issues. I use Time Machine hourly on an encrypted SSD and Arq for remote backups, also encrypted, with Wasabi cloud storage for immutable (90 days) backups.
