This article describes the best practices on how to backup .pst files with SecuriSync.

A Personal Folders file (PST) is an Outlook data file that stores the messages and other items on the computer. Since PST files are regularly pretty large, we advise not to back up PSTfiles with SecuriSync. End-user mailboxes are usually backed up by the mail provider. Also, in most cases, Outlook desktop clients are configured in cached mode, which means that the local PST file only has a subset (last couple of months) of the mail items in the mailbox. As such, a backup of the local PST file would not facilitate a full mailbox backup.

PST file is also a database file which changes frequently, and thus not a good fit for a real-time backup. This file type is excluded by default.

It is recommended to use Outlook Backup feature in order to backup the PST files. Outlook Backup is an optional feature and it is available in HostPilot® Control Panel > Services > Outlook Backup.

To prevent SecuriSync storage issues, we recommend to modify the Backup Policy and use File Type Exclusions feature to prevent users from keeping .pst files in SecuriSync.

You can manage File Type Exclusions in HostPilot > Services > SecuriSync > Backup Policies > File Type Exclusions. Alternatively, it is possible to exclude folders that have PST files from real-time backup by modifying Folder Path Exclusions in HostPilot > Services > SecuriSync > Backup Policies > Folder Path Exclusions.
