What tape library do you recommend?

Question

Iron

Until now, backups were always made to disks, but time is running out, the volume of daily backups is 1.2 TB at the moment, we have to reduce the storage time, I would like to make a remote copy, etc.
Previously, a colleague used some hp libraries (I suspect that they were cheap) with them there was one hemorrhoid, they
constantly broke + a small volume of tapes. There are three drawbacks with a backup to disks:
- Expensive
- No remote backup
- The copy's shelf life is too small
_______________________________
When you don't know something, it's better to ask.
Please advise tape library
- LTO4/5
- vendor preferably HP
- fast backup restore (fantasy?)
- backupexec compatible
- on disks I would like to have a copy of increments per day + weekly, and also transfer all this to tape.
Once again, I will clarify the volume of 800 Gb on a weekday, 1.2 Tb on the weekend, in the future 1 Tb on weekdays, and up to 2 Tb on the weekend.
I would like to store a weekly copy for a month, a monthly copy - for take-out - half a year - a year, an annual - for take-out -5 years
. There is no backup window, but at night the load on the backed up servers is small.
More requirements
- the price is not the main thing, the main thing is reliability - you need advice from those who use this
- also how to calculate how many tapes you need, how long the tape life is.
- also advise tapes
I would like to know the approximate budget - the cost of the library and tapes.
Millions of dollars will not be given, but in rubles they can give a lot (within reason).

Answer 1

Take HP Autoloader 1/8 G2 LTO-6 Ultrium (price depending on the interface from 200,000 rubles) autoloader for 8 cartridges with a 1U drive.
Cartridges 2.5 TB (without compression) 6.25 TB (with compression), compression is an extensible concept (I have lto5 1.5 \ 3 TB recorded on tape from 1.6 to 2.2 TB, now I would take LTO-6 ).
"also how to calculate how many tapes you need, how long the life of the tape."
How many ribbons. 1 TB weekdays (6 days - 3-4 cartridges, replacement every half a year = 8 per year), 2 TB weekends (1 cartridge per week, 4 per month, you can replace in a year = 4 per year), 2 TB per month (12 per year, you can buy WORM), 2 tb per year (1 per year, you can buy WORM), total 8 + 4 + 12 + 1 = 25 cartridges per year (you can reuse monthly cartridges) 25x5000 rubles = 125000 rubles / year. Looks like I wasn't wrong.
Life time. I looked at the data on cartridges for a long time, but in favorable conditions with a single entry hp for Lto6 is 30 years, with multiple entries, focus on the plate from the wiki en.wikipedia.org/wiki/LTO

Answer 2

The budget will be expensive.
At one time, they wanted to buy a tape library, and the price increased to 1.5 lyama.
As a result, we bought a vault, put 12 pieces into it. 3.5" disks for 4tb - SATA. We assembled it in a REID and got a crazy volume. In
terms of speed, the tape didn’t lie around. And the disks are cheaper to replace.
and there is no fuss with disks, unlike
tape.Tape is yesterday.Now disks are of such volumes that tapes are no longer relevant.One
moment, HP has stopped making storage devices with SATA support since this year.So you will either have to look in warehouses, Or change vendor.
