What to use for centralized backup (backup server)?

Question

Backup

Hello.
Tell me, what do you use for backup in corporate networks?
There are working machines, servers, virtual machines, terminals, video surveillance, network settings, and so on.
I would like to backup all this somehow, centrally, to monitor all backups from one application.
What are the solutions? I only found acronis backup, but it seems to be very expensive, and there may be free or better solutions.
There are no special requirements for the backup system, just backup the system once a week, for example, and store it on some kind of shared disk.
PS
In the end, I tried a lot of things. And I settled on Veeam backup. I dealt with it for a long time (I am still studying something), I could not set it up, BUT in the end it works well. And very convenient!

Answer 1

Veeam Agent is free and available for Windows and Linux, installs into the system, supports backup chains, complex schedules, and compresses/defrags backups. Virtual machines in which the agent is not installed can be backed up using the hypervisor. I'm stacking so far, unfortunately, on a restricted SMB folder.

Answer 2

Rsync for linux and DeltaCopy for windows. The protocol is the same, so it doesn't matter what will be on the backup server itself - Windows or linux.
You can also consider installing rsnapshot on a linux server. The clients will be the same.

Answer 3

Symantec BackupExec aka Veritas BackupExec

Answer 4

Virtual machines - via Nakivo
Configs, database, mail - with separate scripts on the shelves
In no case on a shared disk. A server with backups should be available to a very limited group of people.

Answer 5
