Backup Repositories

A backup repository is a storage system where you can keep backups created by your backup jobs. Veeam Backup for Microsoft 365 uses Extensible Storage Engine (ESE) databases, also known as JET Blue, to store backed-up data.

You can add the following types of backup repositories to the Veeam Backup for Microsoft 365 infrastructure:

  • A local directory on a backup proxy server.

A default backup repository is the C:\VeeamRepository directory on a computer with Veeam Backup for Microsoft 365.

  • Direct Attached Storage (DAS) connected to the backup proxy server.
  • Storage Area Network (SAN).

A backup server must be connected to the SAN fabric using hardware, virtual HBA or software iSCSI initiator.

  • Network Attached Storage (SMB shares version 3.0 or later).

Experimental support.


Consider the following:

  • Veeam Backup for Microsoft 365 does not support encryption at-rest for these types of backup repositories.
  • You can store your backups on volumes encrypted using the BitLocker technology if it applies to your system. After encryption, the I/O rate of the volume may change.
