Global Mailbox configuration
files and the payloads that are contained in the mailboxes are stored on the shared disk stores. The
disk is active because files are uploaded and deleted rapidly from the system.
About this task
Back up the shared disk regularly. The frequency of backups is determined by your Recovery Point
Objective (RPO). The RPO is the maximum time period in which data can be lost during a failure.
Procedure
To back up and restore a shared disk, complete the following steps:
-
Back up the configuration files and the mailbox payloads in the following directories:
- Configuration files: config
- Payload files: 1st_provisioned_* and global_mbx_*
Payloads are replicated from one data center to another. If a file is not replicated to the data
center that had a failed disk, it is replicated after the disk is brought back online. If the failed
disk had the only copy of a file because it was not replicated yet, it might be lost if it was
received in the RPO window. Payloads that are uploaded between the last backup and the restoration
are lost. For more information about restoring lost files, see Processing files in the surviving data center.
