Select Backup File Delivery Method and Format

On this page

Overview

With On Prem MMS Backup, you can restore from a stored snapshot or, if you are restoring a replica set, you may build a custom snapshot reflecting a different point in the last 24 hours. For all backups, restoring from a stored snapshot is faster than restoring from a custom snapshot in the last 24 hours.

Once you select a backup-enabled sharded cluster or replica set to restore, the next step is to select the delivery method and file format.

Procedures

Select Backup File via Secure HTTP (HTTPS)

In the Select Restore Destination window, select Pull via Secure HTTP (HTTPS) to create a one-time direct download link.

Select Backup File via Secure Copy (SCP)

In the Select Restore Destination window, select Push via Secure Copy (SCP). You can grant access by supplying MMS with a username and password to your server, or you can provide a username and grant access via SSH public key.

To grant access via SSH public key:

1

Select the Settings tab, and then select Restore Settings.

2

Enter a passphrase and click the Generate a New Public Key button.

On Prem MMS Backup generates and displays a public key.

3

Log in to your server using the same username you will supply in your restore request.

4

Add your public key to the authorized hosts file for that user.

For security reasons, you should remove the public key from the authorized hosts file once you have obtained your backup file. The authorized hosts file is often located at ~/.ssh/authorized_keys.

Note

For security reasons, you should remove this public key from the authorized hosts file once you have obtained your backup file.

Select Backup File Format

In the Select Restore Destination window, select Individual DB Files or Archive (tar.gz) as the Format:

  • Select Individual DB Files to transmit MongoDB data files produced by MMS Backup directly to the target directory. The individual database files are faster for On Prem MMS Backup to construct, but require additional file space on the destination server. The data is compressed during transmission.
  • Select Archive (tar.gz) to deliver database files in a single tar.gz file you must extract before reconstructing databases.
