Backup is not backup unless it is tested
Many businesses assume that files on another computer, external drive, NAS device or cloud folder are safely backed up. A failure, accidental deletion, malware or ransomware incident may reveal that jobs were not running, critical data was excluded or nobody knows how to restore it.
A reliable backup system defines what is copied, how often, where copies are stored, who has access, how long versions are retained and whether data can be restored when needed.
Business backup is therefore part of IT maintenance, security and business continuity.
Which business data should be backed up
- business documents, invoices, quotes and contracts
- accounting data and business application databases
- shared folders and NAS or server files
- email archives
- Microsoft 365, OneDrive and SharePoint data
- data on key employee computers
- images, scans and business documentation
- network equipment configurations
- licences, passwords and IT documentation
Common risks without proper backup
What NBG TEAM checks
Local backup, cloud backup or both
There is no single solution for every company. Local NAS backup can provide fast restores, a cloud copy protects against office-level incidents, and a combination of local and off-site copies is often the best approach.
Important data should not rely on one location. If originals and backup are in the same office, one serious incident can affect both.

Local backup is useful for:
- fast recovery of large files
- computers, shared folders and NAS or server systems
- businesses that work with large files
Cloud backup is useful for:
- an additional copy outside the office
- protection after theft or physical damage
- remote users and Microsoft 365 data
- recovery when local equipment is unavailable
Backup for NAS and servers
NAS devices and servers often hold the most important company data, but they are not automatically safe. Drives fail, users delete files, ransomware encrypts shares and incorrect permissions increase risk.
We check RAID, drive health, shared folders, access rights, schedules, versioning and restore capability.

Backup for Microsoft 365, OneDrive and SharePoint
Microsoft 365, OneDrive and SharePoint support file and email work, but do not replace every backup requirement. Retention, access, deletion and recovery after user error, account compromise or incorrect synchronisation must be reviewed.
Businesses that depend on Microsoft 365 should separately assess backup for email, OneDrive and SharePoint data.
Backup and ransomware protection
Ransomware can encrypt computers, shared folders, NAS devices and network drives. A backup continuously accessible to the same users and devices may also be compromised.
Business backup needs protected access, versioning, a separate location and a clear recovery procedure. It does not replace antivirus, MFA or security rules, but it is essential to recovery.
Backup as part of monthly IT maintenance
Backup is not configured once and forgotten. Jobs, errors, new users and folders, and restore capability need regular checks.
It is most useful as part of managed IT maintenance, with a responsible person tracking status and changes alongside ongoing IT support for businesses.
When emergency IT support is needed
If data is deleted, a drive is failing, a NAS is unavailable, a server is down or ransomware is suspected, request emergency IT support. Random recovery attempts can reduce the chance of successful recovery.
