Cloud Backup
Your data, always recoverable.
Castle Cloud Backup protects Microsoft 365 and Google Workspace independently of the platforms themselves — so a deleted mailbox, a ransomware attack or a leaver’s missing files is a quick restore, not a disaster.
Backups up to hourly
Automatic backups as often as every hour, plus on-demand backups whenever you need one.
Unlimited retention
Keep every version for as long as you need — set retention to match your compliance rules.
Point-in-time restore
Browse your data exactly as it was on any date, with unlimited recovery points.
Single item or everything
Restore one email, one file or a whole account — back to where it was or somewhere new.
Ransomware-resistant
Immutable backups that can’t be altered, and pre-emptive backups if attack activity is detected.
Full-text search
Search inside emails and documents to find what you need in seconds, then preview or export it.
Leavers archived automatically
When someone leaves, their mailbox and files are kept — without paying for their licence.
Stored in the EU
Backups held in EU datacentres, with restore-only admin roles and a full audit log.
Every place your data actually lives.

Microsoft keeps it running. Your data is your job.
Cloud platforms work on shared responsibility: they keep the service up, you protect what’s in it. These are the gaps a separate backup closes.
Read: RTO and RPO explained →Accidental deletion
Deleted items are only kept for a limited time. Notice too late and they’re gone.
Ransomware
Encrypted files sync straight back to OneDrive and SharePoint, overwriting good copies.
Leavers
Remove a licence and that person’s mailbox and files are deleted with it.
Malicious changes
A compromised or disgruntled account can delete data across the business.
Protected without the hassle.
For Microsoft 365 and Google Workspace there’s nothing to install. We connect your accounts, run the first backup and look after it from there.

Doesn’t Microsoft already back up our Microsoft 365 data?
Microsoft keeps the service running and protects against its own hardware failures, but protecting your data is your responsibility. Deleted items are only kept for a limited time, ransomware can sync encrypted files over good ones, and removing a licence deletes that user’s data. An independent backup covers all of that.
How often are backups taken?
Automatically, up to every hour, and you can trigger an extra backup on demand at any time — before a migration or a big change, for example.
How long do you keep backups?
As long as you need. Retention is unlimited, so we set it to match your own policies, your insurer’s requirements or any industry rules you work under.
What happens to a leaver’s data?
Their account is archived automatically, so their mailbox and files stay recoverable — and you don’t need to keep paying for their Microsoft 365 licence.
Can ransomware get to our backups?
Backups are immutable and stored separately from Microsoft 365, so an attacker in your tenant can’t alter or delete them. If attack activity is detected, an extra backup is taken straight away, and admin roles can be limited to restore-only.
Where is our backup data stored?
In EU datacentres, so your data stays in the EU — which makes GDPR straightforward. We can provide retention reports for audits and insurers on request.
