Backup Solution - Recommendations

OK so I've been told by BackupAssit the reason for the failing backups is the Disk is about to die.
Question is which disk! I have a 8x 300GB SAS in RAID10. My Dell iDRAC is showing green across the board.That doesn't make sense as BackupAssist should be talking to the RAID array, not individual disks. If the RAID array shows errors to applications down the chain it means that it has already failed. A failing disk could not be detected by an application. Not even a failed disk is detectable.

Why do they think that?
What are they seeing that the DELL diags are not? (Are these DELL drive?)
There an Event ID 52 disk (on disk DR2) in the event logs for the HyperV server. But I think disk 2 is the RDX drive.
How would Hyper-V be seeing individual disks in a RAID array? Is this hardware or software RAID?

Seems to now over the last 2-3 weeks.Might be time to try a different RDX drive, I suppose! Do you have more than 1? Thank goodness they are pretty reasonable.
We looked at RDX, and were using it for BackupExec before we switched to our Datto device.
they should be cheap, it's little more than a USB adapter

Not to hand no. Might need to buy one and send it up. But that's why I'm considering alternatives.
Good time to consider tape. Any backup media that you have, you generally need to have multiple drives to handle it for reliability purposes.

You could even keep using your RDX drive for that. (Though I wouldn't recommend it due to the cost difference between RDX cartridges and equivalent USB drives.)
RDX drives are designed to be plugged and unplugged regularly and are shock resistant for travel. Those are their selling points. USB drives are better if they never move anywhere and are rarely plugged and unplugged.

I typically think if you are making, say, a monthly backup, use a USB drive. They are at lezst half the cost.
If I had a drive I was carting back and forth every week or so, I'd probably still go USB, and just do it more regularily.

Wait?
Did you just say tape?
Wha whaaaa? -

Wha whaaaa?RDX is just drives mimicking tape. Why not use actual tape?

Difference is in how you have to card it around. USB drives require a lot more care.

Because drives are better/faster/cheaper?

Agreed.
But if you are a little careful, you might be OK.
Or get a USB drive that can take a little more beating than normal.
Just saying there is a huge premium for RDX.

Than tape? Where have you found these magic drives? What RDX drive is faster or cheaper than LTO?

Where do you find this USB drive?

LTO is $8/TB. That would mean a 4TB drive with far better than RDX speed or reliability would need to be $32 for normal sizes and $64 for the biggest on the market. Tape looks to be like 1/10th the cost of drives.
-
LTO price reference. And this is from over six months ago. It keeps going down and new, larger formats are due out soon.

I mean that the smaller passport-type drives are easier to carry around than the larger enclosure type drives.
None of them can take real beating, per se.
But if I buy it, unbox it, do the backup, rebox it, and take it somewhere to store, I think that is a much better option, cost-wise.

How much does the actual drive cost?
