More and more business data has been making its way to the cloud, and quite often, we see clients adopt an out-of-sight, out-of-mind approach to worrying about data backups. When data was stored in on-premise servers, backups were done vigilantly and regular recovery testing was often scheduled. However, once data moved off-site, the importance of backups and testing becomes forgotten or ignored.
For example, more and more businesses have moved to Office 365 for email, collaboration, and file storage However, while Microsoft does backups, they do so for their benefit, not yours. In fact, the service agreement for their standard subscriptions does not specify a retention schedule for backed up data. Need to recover a lost email message from three months ago? A granular recovery from an on-premise Exchange server may have been possible if backed up with a solution such as our ProtectSuite Backup and Recovery Solution (BRS), but such a recovery would likely not be possible natively from Microsoft Office 365.
Microsoft is ultimately responsible for their service – you are responsible for your data.
Cloud-to-cloud backup solutions exist to take multiple backups per day of your Microsoft Office 365 data and data from other select cloud platforms and replicate it to a 3rd party backup infrastructure. Remember, even if you have email archiving enabled, archiving and backup are not the same, and any non-email data, such as data from Sharepoint, OneDrive, OneNote, or Teams, would not be part of the archive data set.
Cloud data backup still needs to be part of your data backup and recovery strategy. You’d do it if it were on-premise, so…?
