Backup Office 365

Backup Office 365

The Office platform does not allow granular recovery. A mailbox has a retention of several days, nevertheless it is not possible to restore a mail, folder, tasks, contact,…
Veeam Backup for Microsoft Office 365 can be installed on a physical or virtual machine. It is possible to implement the following features :

  • Retrieving mailbox elements.
  • Recovered e-mails can be saved as a file, sent as an e-mail attachment or exported as a PST file.

How it’s works ?

When the backup task is initialized, a creation of the mailbox database file and the auxiliary files are created. This creation operation is performed in the corresponding subfolder (named < year_of_last_modification >) in the repository, creating a database. For this purpose, the expandable storage engine for Windows (ESE engine) is used.

Initial execution of the backup task creates a full backup of the entire mailbox contents for the selected mailboxes. All data during the working session is transferred using the backup proxy.

For subsequent runs of the backup task, synchronization has executed between the data repository structure information, mailbox data, and the current status of the Exchange organization. This is done using Web Exchange services.

Each time a job is successfully executed, a new restore point retains the corresponding status of the mailbox dataset. Thus incremental backups are performed, Veeam performs a detection of changes in the mailbox data (modification, new mailbox). This detection is performed since the last execution of the backup task thereafter, an incremental backup is performed
