What is the best way to store backups? And is it advisable?

Question

System administration

I've been wondering for a long time what backups can be copied to? On streamer cassettes? If it's profitable, what's a cheap/good multigb kit? Or are there more modern ways in the form of external drives?
How do you organize copies of backups in your organization/enterprise? And do you do it at all? Why?

Answer 1

Until recently, in terms of price / quality, the server with 2TB disks and the fifth or sixth raid was the most profitable. Disks in the states for 50 are already like that. The server is assembled here, a good case with a powerful block is taken. A good branded mother, that's all. There is no need to chase hardware controllers. (we have been operating for almost ten years several dozens of serious expensive servers and non-name servers and self-made ones. So, the scheme I described is cheaper and more practical ... That is, storage for six TB costs somewhere around 700-800. I mean 5 disks of 2TB each. 4 in work , one replacement... But now a cheaper solution from Hedzner, where a server with six teras costs 49 euros per month, take a pair for reliability, make a cluster and forget about everything!

Answer 2

Disk array. A simple server for 24-36 disks will cost about 200k-300krub (this is on good hardware), if you wait, you can make <100k quite easily.
In the minimum version - a desktop with several screws in a soft raid. Why in software? Because if something dies, you can stick disks into the first server you come across and read the data, and not run around the city in search of that dead raid model that will read its metadata.

Answer 3

External hard drives are quite an acceptable option ... The price of drives is now small + technically easy to implement.

RAID5/6 on the iron controller.

cheaper and more convenient disk storage. The streamer is slow and expensive. But the tape is more reliable. I counted something like 300 thousand for 3Tb.

Answer 5

PC + controller + RAID5 screws 3 TB each + external screw for saving a copy month, quarter, half year, year
backup setup once a week full, every day incremental

Answer 6

We store backups in the Amazon S3 service. It's pretty cheap to store there. Plus, you don't have to worry about backup discs getting corrupted.

Answer 7

A streamer, for example, 400 GB + a set of cassettes can cost $ 100k
cheaper and it’s easier to make backups on a NAS - my backup first goes to another physical hypervisor, from there to a tape.

Answer 8

How do you organize copies of backups in your organization/enterprise? And do you do it at all? Why?

At one enterprise, a 500GB portable screw is inserted into the server with 1c, and at the other there are no backups ... All hands do not reach :)

Answer 9

in general, either external screws, or raid1 of 1..3 TB disks

Answer 10

If locally, anything that can be called a NAS will do. Though a basin with screws and Unix, even a home media player, even a specialized piece of iron. Well, or yusb-screw.
If remotely - a remote server with raised ftp / ssh / nfs. Mandatory in a different place in relation to the server with the main data.
There is also a habit of encrypting gpg backups.
