Backup Office 365 Exchange Online Emails and Mailboxes

to Multiple Destinations and Public Cloud

As more and more businesses migrate from on-site applications to the cloud applications in recent years, the Office365 adoption rate is soaring high. However, data loss caused by human errors and cyber attacks becomes the main concerns. With CloudBacko Pro / Lite, you'll have the best backup solution to protect your emails on Office 365 Exchange Online by backing them up to local storage or another non-Microsoft cloud automatically everyday. It gives you peace of mind about your Office 365 Exchange data as you can restore your emails, contacts, calendars anytime just through a few simple clicks.

Why Office 365 backup is important

Moving business workloads to the cloud becomes prevalent nowadays, and millions of organizations have migrated their on-premises Exchange email infrastructure to Office 365 Exchange Online. With the assumption that data running in the cloud is always available, people may not realize their Exchange data could ever be lost. After all, Microsoft guarantees 99.9% uptime and the Office 365 data should be secure within their data centers. The unfortunate fact is, Office 365 data may not be as safe as many think. If you are serious about your Office 365 Exchange Online's data, these are the 4 main reasons to back it up:

Data is not covered by Office 365's SLA

Accidental deletion by user

Ransomware attack

Litigation hold doesn't equal backup

Backup all mailboxes in one shot

Administrator of your company's Office 365 account is able to back up all or select mailboxes or individual items within a mailbox with our CloudBacko Pro software. Backing up "Public" folder is supported by CloudBacko. For individual Office 365 users, they use CloudBacko Lite to backup their own mailbox items.

Full mailbox or brick-level backup

CloudBacko enables Office 365 administrators to back up all or selected mailboxes under their accounts with just a few clicks. Besides the full mailbox, you can also backup and restore brick-level items such as emails, contacts, calendars and tasks.

Local and offsite backup to prevent data loss

To avoid disastrous data loss, the best practice is to keep at least 3 copies of your data:

  1. one on your original Office 365 environment;
  2. one to local storage such as a NAS device within your office;
  3. another one to offsite storage, either your FTP/SFTP server or another non-Microsoft cloud storage, as an additional protection.

Other than Microsoft Azure or OneDrive, CloudBacko Pro supports a wide-range other free and paid public cloud storage, including Amazon S3, AWS compatible storages, Google Cloud Storage, Google Drive, OpenStack, Rackspace Cloud Files, and Dropbox for you to choose.

Secure data encryption

When backing up your Office 365 to another cloud, since it is not your own environment, make sure to enable encryption to prevent somebody from stealing your data. With CloudBacko Pro, no lazy encrypting keys such as "abc123" or "123456" will be used. It provides unbreakable encryption to your Office 365 backup, as all the data and filenames can be encrypted with an AES 256-bit truly randomized key. Even a 10.51 Pentaflops supercomputer needs 3.31 x 1056 years to crack such key. Therefore, hackers will not be able to crack your backed up data on the cloud.

Set it to run automatically, and forget it

You need a backup solution that can automatically run once or several times a day by itself based on your pre-configured schedule, so that you can restore to the latest version when needed. CloudBacko Pro allows you to define your own schedules to run the Office 365 email backup (e.g. after work everyday).

Keep multiple versions of backup

It's always good to keep mulitple backup versions of your Office 365 backup, so that when you realize it's not the latest backup you want to restore to, you can still choose an earlier version to restore. With CloudBacko Pro's powerful retention policy setup, it is simple and flexible to define various versioning rules to suit your version retention needs.

Restore to original, different mailboxes

Backed up emails and mailbox items can be restored to original or different user account in the same Office 365 domain, or to an alternate domain.
