About Castleknock Computers

We at Castleknock Computers can provide secure data backup service for you, we have partnered up with MSP Backup and the launch of their new product Office 365 Backup and really excited the markets and has filled a gap that was unfortunately vacant for years! What does MSP Office 365 Back up offer?

Protection against data loss: Users can often unwittingly (or purposely) delete important emails, or OneDrive or SharePoint files. If this happens, MSP Backup offers the ability to quickly search for and recover what you need.

Access to email for ex-employees: If employees leave and you don’t want to continue paying a subscription fee simply to store their email and shared documents, MSP Backup for Office 365 offers an additional way to retain and access this data.

Support for compliance: If you are responsible for an organization that falls under regulations with data-retention requirements, MSP Backup is designed to help you retain and archive critical data.

Easy management: With MSP Backup for Office 365, you can manage your Office 365 Exchange, OneDrive, and SharePoint backups from a single web-based dashboard.

Automation: MSP Backup helps you strike the right balance between automation and control. You can manually select which accounts and mailboxes you want to protect, or automatically add newly created Office 365 accounts to the backup schedule.

Point-in-time restore: Exchange mailboxes are automatically backed up every four hours, and OneDrive and SharePoint accounts every six hours, giving you multiple restore points every day. Choose the one you want, and recover fast.

Retain and recover Office 365 Exchange data for up to seven years.

Retain and recover Office 365 OneDrive data for up to six months.

To summarise: All Companies and Sole Traders are obliged by Company Law, Revenue and GDPR to ensure that adequate systems are in place on your IT Setup and that computers, laptops and servers are to be maintained and updated on a regular basis, Data Back up is a necessity for any business in today’s world of Internet Fraud. Give us a call today and we will call out and give you a free no obligations assessment on your existing setup and advise you what we would recommend based on our years of experience and a record of having not one customer’s data being compromised or stolen since they let us manage their IT Systems!
