Is OneDrive or a folder on a second disk a backup?
No. Sync deletes the file in both places when someone deletes or encrypts it. Backup keeps a separate version that ransomware and a mistake cannot overwrite.
Why sync is not protection
Where does the offsite copy sit?
Outside the office, encrypted. The exact place is set in the project. One condition: a flood or a theft in the server room does not wipe the only copy.

How often do you test a restore?
Regularly, as part of care, and always at the end of a rollout. The result goes into the report: what comes up and how long it takes. We do not leave that for the day of a failure.
What we measure in a test
How does backup differ from archiving?
In purpose and in cycle. A backup exists so you can return to the state before a failure, so it keeps few versions and overwrites them quickly. An archive exists so that years later you can find a specific document an authority or a client asks for, so it keeps one version but for a very long time. Neither replaces the other, although they often use the same tool.
Retention periods
Does Microsoft 365 back up our mail?
Not in the sense most companies mean. Microsoft looks after the availability of the service and makes sure the data is not lost through its own fault, but recovery after a user deletes something rests on a bin with a deadline: fourteen days by default in mail, up to thirty once the setting is changed, ninety-three days in OneDrive and SharePoint. A copy independent of those deadlines has to be bought separately.
What the cloud covers
What does backup cost for a company?
It depends mainly on how much data there is and how long it has to sit, not on the number of workstations. That is why we give a price after the review, which shows the real size and what is being copied for no reason. The review itself is free, and if it turns out the current copies are fine and only need testing, we say so plainly.
IT costs under control
We have a NAS in the server room, is that enough?
As a place for a local copy yes, as the whole answer no. A NAS standing in the same rack as the server shares its fire, flood and theft, and if it is attached with the same passwords it shares the ransomware too. We treat it as the first stop, from which the copy travels further, off the premises.

Ransomware encrypted us, where do we start?
Not by restoring the copy, because restoring onto an infected environment ends in a second encryption. First the affected machines are disconnected, you establish how they got in and check that the copies have not been touched, and only then do you bring data back. We cover the first hours separately, because that is when most of the damage is done.
