![]() The full Backblaze report is available here. For 25.64 total (over 12 years), they store your data with significantly more redundancy than you when you put one copy of your dataset on one hard drive. Of course, we won’t know for another 6 to 8 years if that’s true. The helium is thought to also increase lifespan by reducing said friction. Something else to consider – although it wasn't brought up in the Backblaze report – is that new high-capacity drives are filled with helium to reduce the friction from so many platters spinning in the tight space. That means it can deploy much more capacity in the same space, and the eight-year-old Seagates are headed for recycling. Klein said that in 2023, Backblaze plans to replace older drives with 16TB and larger hard drives. The next closest is HGST, which Western Digital owns, at 0.81% AFR. Western Digital earns bragging rights for the lowest failure rate at just 0.20%. However, Backblaze only has 79 of this model in service, and these drives are used as spares to replace 8TB drives that have failed, Klein noted. You can force the rescan by holding down the ALT key and clicking. It will slow your computer down for a few minutes while it scans all your drives. There is a way to force an immediate rescan. In 2022, only one hard-drive model in Backblaze's fleet had zero failures: the 8TB Seagate. When you plug in an external drive, it may take Backblaze anywhere from 1-120 minutes to schedule the files on the external drive to be backed up online. You could make a good case that, for us, many Seagate drive models are just as cost effective as more expensive drives," Klein said. Their failure rates are typically not high enough to make them less cost effective over their lifetime. You can get in touch with me and I can help address these problems if you think that they’d impact you."In general, Seagate drives are less expensive, and their failure rates are typically higher in our environment. ![]() This means that if you changed a large file multiple times during the day, Backblaze would only backup one copy every other day. You’re unlikely to have (m)any files over 30 MB anyway, except your Outlook data file and perhaps some PowerPoint slides. However, it will take one revision every 48 hours for files over 30 MB in size. Backblaze will backup, and keep revisions, of all files whenever they are created or updated – and it’ll keep every revision for 30 days.For other people though – where you download email via POP3 and store it in PST data files, I have a workaround which can take a copy of your data files and lets Backblaze back those up. Not everyone who uses Outlook needs its data file to be backed up (if you use Microsoft Exchange, or email via Office 365 or Google G Suite, you don’t). Essentially, if Outlook is open, Backblaze can’t back up its data file. The only files that regularly fall into this category in my testing are Outlook PST data files. Backblaze cannot back up a file that is “exclusively locked”.Even external hard drives or USB flash drives: you can back up anything that is connected directly to your PC, but network drives – no. If the hard drive is on your PC, you can back it up. You can’t trick or beat it, it knows what you’re trying to do, and has been taught how to identify a shared network drive. Backblaze will not allow you to back up a network drive.Each of the three things it can’t (or won’t) do can be worked around once you know that they’re there. Backblaze has three small downsides – so make sure that you are happy with them before you jump in. The overall average failure rate for Q1 2023 was 1.54, a rise from 1.21 in Q4 2022 and 1.22 in Q1 2022. There were good and bad things about every backup system that I trialled.
