I have critical server that running the local company system, that have system backup and company files and business documents with critical and important severity.
I'm planning to create a Network attached server, however this server weather its just a VM attached to another server or computer, or physical hard disk like multi Bay device attached to the network
Or create a cloud instance then sync the important files to be uploaded and make a frequent backup for the main server
What is the best approach to apply the Backup Server
Local Server that connected to network
Local VM that mirror the important data and store them in hard disks
Local & Cloud multi bay hard disk that sync the data and store them on the cloud too
Online Cloud backup, install agent on the main server to sync the important files to be transfer for backup and archiving (Expensive solution)
