|I'm still reading that those who need to perform massive backups still prefer tapes. I've always been a skeptic.
Isn't everything about a tape backup solution proprietary?
If you have a specific type of tape, you have to have the matching drive. The reverse is also true, if you have a specific drive, you can't just use any tape in it. I suppose there might be compatible makes/models (of both drives and tapes), but things are still not as interchangeable as "hard drive A vs hard drive B".
And then the software tends to be proprietary, and not every OS can just read any random file from a given tape. If you've done a backup with software XYZ, you have to do software XYZ to do the restore. Imagine finding a bug in the restore portion of the software, and the manufacturer has gone out of business years prior.
That would worry me, unless I had an unlimited budget and could purchase all the redundancy I'd need to be comfortable. How many tape drives is that? I have no idea. Imagine having stocked up with 5 spare tapes drives...with a SCSI interface.
Obviously big business has different needs than I do. I'm perfectly happy doing "xcopy backups" to multiple hard disks. No proprietary software, you can access any file in any folder instantaneously, no matter what OS you mount the drive with (within reason), hardware interfaces will remain standard for years if not decades before being deprecated, you can buy them in various capacities from different manufacturers, and they're relatively cheap.
I tend to buy them in sets of 3 - one live, a disconnected backup, and an off-site backup. When I outgrow a set, it becomes more or less a permanent archive of "things as they existed at that point in time".
When SATA became the standard, I had plenty of time to migrate the data from IDE drives to SATA drives. Whenever SATA gets replaced, I'll just do the same.
The non-starter is when you have massive amounts of data. I try to keep my entire backup set on a single drive, and I currently have a trio of 16TB drives. If my archive suddenly grew to double that, I wouldn't have a "single-drive solution", as 32TB drives are still a long way off. I'd hate to have to maintain a RAID, and multiple backups of it...
