Backing up data

Defining a backup-and-recovery strategy

The purpose of creating Microsoft 365 backups is to recover a mailbox or site contents that are damaged from media failure or data corruption. Reliable use of backup for recovery requires a strategy that maximizes data availability and minimizes data loss, while accounting for defined business requirements.

A strategy is divided into two pieces: a backup piece and a restore piece.

Your backup plan should define at what intervals the backups are performed, how backups are stored, how long backups are retained, and how the backup media are reused.

The plug-in provides the following types of backup:

Full Backups only: You can choose to perform only Full Backups if the backup size is small, the backup window is not an issue, or storage media is not a constraint. In such scenarios, you can schedule Full Backups every night or every N hours depending on the frequency of updates.
Full and Incremental Backups: For quicker backups and minimum use of storage media, you can include Full and Incremental Backups in your strategy. For example, you can schedule Full Backups every Sunday and Incremental Backups every day or every N hours depending on the frequency of updates.
Continuous Data Backups: Continuous data protection (CDP) occurs when NetVault takes an initial full backup of a selection set and then takes a series of incremental backups to capture the changes of the selection set before it combines the backups into a synthetic full backup.

Adding patterns to use for exclusion and inclusion

From the backup selection tree, you can create and store patterns of mailboxes, mailbox folders, users, sites, and teams that you want to include and exclude for all selected user mailboxes that you back up and for each tenant. When you specify patterns to exclude or include, or both, the plug-in stores them with a Backup Selection Set. When you submit a backup job, you can select the set with the stored patterns. The plug-in then populates the backup list with mailboxes whose folder names meet the specified inclusion and exclusion patterns. There is no limit to the number of patterns that you can specify. Be aware that the plug-in gives priority to exclusions.
