There is always need for more :-)
We currently have a little over 50TB in house that's just about filled up. Looking to get another 20 pretty shortly I believe. We have (5) Solaris boxes handling our backup duties..(1) Master Server (4) Media Servers. We run Veritas Netbackup Center v4.5 that we're upgrading to v5 shortly. Total of (4) tape silo's. (2) SDK 9710's & (2) SDK 9730's. All have DLT's in them. A total of 18 tape drives among the 4 of them, that we'll be adding another 4 drives to the mix. We still have 2 bays available in the 9710's. The DLT's are actually towards being an end of life product which is also why we're trying to snatch up a few more of them pretty soon.
That of any help?? hehehe
Kind of :-)
How much can store one of those tapes?
Years ago, for the 8086 there were floppies autchangers: you put a stack of a hundred floppies, and it was automatic. Or you used a tape, that at first was larger than the HD capacity. I wonder if there are tape autochangers, or CDrom autochangers.
Back when I had a 30 MB drive, I used to back it up to floppies. Then when I got my 386, it originally had a 120 MB drive. I used to back it up with one of those QIC-80 drives, attached to the floppy controller. I could generally get a couple of full backups to one tape. Then I got a 540 MB drive and a 2 GB and now that tape drive was no longer so useful. I could have bought another hard drive, for less than the tapes to backup one copy, would cost. As for those huge systems, you can use tape changers or just mirror to a second set of drives, preferably at another location.
