Back up and Restore
You can back up and restore system configurations, mailboxes, and emails of Synology MailPlus Server.
To back up system configurations:
With Hyper Backup, you can back up mail system configurations to a Synology NAS compatible with Synology MailPlus Server.
- Launch Hyper Backup on the source Synology NAS.
- Click + in the bottom-left corner to create a data backup task.
- Select either type of backup destination:
- Local folder & USB: System configurations will be backed up to the local Synology NAS or an attached USB/SD storage device.
- Remote NAS device: System configurations will be backed up to a remote Synology NAS, where Hyper Backup Vault runs.
- Specify the remaining settings (see instructions here) to finish the task setup.
- When prompted to select an application to back up, choose Synology MailPlus Server.
- When the task is complete, configurations in the following pages will be backed up:
- Domain
- Mail Delivery
- Service
- Security
- Auditing
- License
- Account
To sync mailboxes and emails:
With Shared Folder Sync, you can sync all mailboxes and emails to a Synology NAS compatible with Synology MailPlus Server.
- Go to Control Panel > Shared Folder Sync on the source Synology NAS.
- Create a folder-sync task for the MailPlus shared folder (see instructions here).
- When the sync is complete, you will have all the mailboxes and emails on the destination Synology NAS.
Note:
- Do not use Cloud Station Server, Cloud Sync, or Synology Drive for the backup. Their two-way sync feature might cause data corruption.
- If a MailPlus shared folder exists on the destination Synology NAS, the backed-up folder will be automatically renamed to MailPlus_1:
- To use data in MailPlus_1: Manually move them to the MailPlus shared folder.
- To avoid account errors: Connect the destination Synology NAS to the directory server (e.g., LDAP server or Windows AD domain) used by the source.
To restore system configurations, mailboxes, and emails:
- Go to the destination Synology NAS, where the backed-up system configurations, mailboxes, and emails are stored in local shared folders.
- Launch Hyper Backup.
- Restore the backed-up configurations from the local shared folder (see instructions here).
- When the restoration is complete, the current Synology MailPlus Server configurations will be overwritten.
- The backed-up mailboxes and emails are readily available without a restoration.
- Go to the License page to enter the license keys. Once migrated, license keys on the source Synology NAS will automatically become invalid.
- After the license migration, the destination Synology NAS will start running the mail service.
Note:
- The backup and restoration feature is supported on Synology MailPlus Server 1.0-164 and above that runs on DSM 6.0 or above.
