Backup
Business backup - how to check if it works?
Backup is not ready because it exists. It is ready when the company can restore operations from it.
Backup works only after a successful restore
The information that a copy completed successfully is not enough. You need to check whether the data is complete, whether it can be restored and whether the company knows who starts the procedures after a failure.
Backup checklist
When reviewing backups, it is worth answering specific questions.
- what exactly is being copied
- how long versions are kept
- where the copy is located
- whether backup covers Microsoft 365
- whether an offline or immutable copy exists
- when the last restore test was performed
RPO and RTO in plain language
RPO means how much data the company can lose at most. RTO means how long the return to work can take. Without these two values, it is hard to assess whether backup matches the real needs of the company.
The most common mistakes
Problems appear when backup covers only part of the data, nobody monitors errors, copies are available from the same account as production, or a restore test has never been performed.
Backup should be assessed through business operations
A backup copy is not the goal. The goal is to restore work after a failure, human error, data encryption or server damage.
Restore test checklist
A backup test should give a reliable answer about recovery capability.
- choose a file, folder or system to restore
- measure restore time
- verify data completeness
- record the test result
- check Microsoft 365 backup
- set the next test date
When backup requires an audit
A backup audit makes sense when nobody knows RPO and RTO, backup covers only part of the environment, restore tests are missing or backup is managed with the same accounts as production.
Examples where backup is not enough
Problems appear when recovery is needed: copies cover only part of data, the last successful job is old or recovery takes longer than the business can accept.
What to do in the first 30 days
Check whether backup matches business risk.
- list critical systems
- verify backup scope
- run a restore test
- define RPO
- define RTO
- check copy separation

FAQ
Common questions
How can backup be checked without risk?
The safest way is to plan a controlled restore test of a selected file, system or scenario in a way that does not disrupt production work.
How often should business backup be tested?
It depends on data criticality, but restore testing should be regular and repeated after major IT environment changes.
Does Microsoft 365 need separate backup?
In many companies, yes. Data recovery after deletion, error or incident requires a conscious backup policy.
Is a NAS enough as backup?
Not always. If it is reachable from the same network and accounts, it may be encrypted or deleted with production data.
