In many companies the backup job is treated as done when the scheduler turns green. The real question is rarely asked the next day: can we reopen the business from this copy? It usually comes up only after a file is already gone.
The database is not the whole story
The database that holds sales and stock is only one piece of what needs protecting. E-ledger certificates, report design files and the other parts the installation needs to run can sit outside that copy. What belongs in the backup depends on the components of your Nebim V3 setup.
Do not build that list from memory. Nebim Akademi training explains which parts to back up and how. For an answer that matches your own installation, ask the Nebim solution partner who supports you.
The only proof is a restore test
The only way to know the backup is complete, and that the hardware holding it is sound, is to restore from it now and then. A file that will not open is not a backup, even if the report says it succeeded. Put the test on a calendar. A rehearsal left until the crisis is already late.
Keep the copies apart
Once you know what to keep and you have tried a restore, the copies still need to be unable to disappear together. The 3-2-1 setup is a plain frame for that.
- Keep three copies of anything that matters. Stopping at two means you are willing to lose that data.
- Keep those copies on two different kinds of media. A disk on the network and a cloud space, or a network disk and a portable drive. If everything on the server is wiped, a second copy that the server itself cannot reach should still exist.
- Keep one copy offline, away from the building that holds the main servers. A locked drive in another building, or a cloud space kept apart from the central system, will do. A second disk in the same server room goes with the first one in the same flood or the same fire. That closeness is not a backup.
