Dire rear
 

Being on-going for almost 2 weeks since change of meds, which have since been changed again.

Very dispiriting :sad:

HDDs
 

In the past month to six weeks I have had two large drives fail. The second was last night. I have backups, but possibly not complete. Restoring what I can ATM. I'll know how much got lost when that completes. I will see tonight, after work.

How old were the drives, and what were their brands?

Please forgive me for this, but you have heard of RAID1/5/6. Correct?

In addition to that, a crontabbed rsync to one or more external and/or remote drives are really good friends to have.

(Sorry for your possible loss.)

An important point; thanks for raising it.

RAID0, for example, is all about speed without any redundancy. You would lose two or more drives worth of storage when only one drive failed in a RAID0 configuration.

About [STRIKE]2years[/STRIKE] [B]3 years[/B], give or take a bit. One is a WD Green AV, the other is a WD Black. The latter is actually an engineering sample from a beta program I was in.

My failure over the last month or two was a touch north of 5 years old. I'm reasonably happy with that lifetime

I am aware of the redundant RAID modes, but have never had a sufficient collection of matched drives to implement. RAID 5 would seem to be the obvious choice, but my understanding is that it should have at least four drives to have decent performance. I actually do have 4 large matching drives, but they are either in the system, or in external USB 3 housings. I would have to clear them somehow to build an array.

Then too, these were both either all or mostly data drives. Recent experience shows that those should be more protected, too. :sad:

I have enough space running around here for backups, but I lack disciplined organization to keep exact track of them. Some things I keep multiple copies of, especially my photography files, which currently take up about a terabyte. Those I have on multiple drives.

I am going to have to get a better system set up. I have software, like Acronis, which would do the on-the-fly backups.

Using the extra drives for multiple backups is a much better use IMO.

I need to be more systematic, but your point is well taken. :smile:
