  1. Enter the following information as needed. To learn about retention values, see Snapshot Frequency and Retention Policy.

    Take snapshots every ... hours and save for ... days

    Sets how frequently, in hours, Ops Manager takes a base snapshot of the deployment and the number of days Ops Manager retains base snapshots.

    Store daily snapshots for

    Sets the number of days that Ops Manager retains daily snapshots.

    Store weekly snapshots for

    Sets the number of weeks that Ops Manager retains weekly snapshots.

    Store monthly snapshots for

    Sets the number of months that Ops Manager retains monthly snapshots.

    Ops Manager takes monthly snapshots every 28 days, not by calendar month.

    Day of Week for Full Snapshot

    Sets the day of the week when Ops Manager takes a full snapshot. This ensures a recent complete backup.

    Ops Manager sets the default value to Sunday.

    Allow point-in-time restores going back

    Sets the number of days that Ops Manager retains oplogs alongside snapshots. To learn how snapshots and point-in-time restores work, see Restore Overview.

    Reference Time of Day (UTC)

    Sets the time of day at UTC from which the snapshot schedule starts. When you change the value in Reference Time of Day, snapshots that are in progress or that are already scheduled remain unaffected. Only snapshots taken after you change the reference time follow the updated schedule.

    The following statements describe how Ops Manager behaves in relation to the value you specify in Reference Time of Day:

    • This value acts as a timer that Ops Manager uses for scheduling and then taking the next snapshot. This value isn't the same as the time when Ops Manager takes the next snapshot, but it is close to it. This value differs from the actual time that Ops Manager uses to take a snapshot by a small interval. You can't control this interval.

    • If you leave this value blank, Ops Manager interprets it as null, starts the timer for scheduling the next snapshot, and then takes the next snapshot after a short interval from the time when it took the previous snapshot.

    • If you change the time value in this field, Ops Manager uses the new time value as the starting time for scheduling the snapshot that will occur after the currently scheduled snapshot. In other words, for each snapshot that is already scheduled, Ops Manager uses the time it already established: either based on the null value plus a short interval, or based on the custom reference time value plus a short interval. If you change the reference time value in this field, the next scheduled snapshot will not happen sooner than the snapshot that is already scheduled.

      To review examples, see Snapshot Frequency and Retention.

Enter the following information as needed and click Submit.

Auth Mechanism

The authentication mechanism that the MongoDB host uses.

MongoDB Enterprise options also include:

DB Username

For Username/Password or LDAP authentication, the username used to authenticate the MongoDB Agent with the MongoDB deployment.

See Configure MongoDB Agent for Authentication or Configure MongoDB Agent for LDAP.

DB Password

For Username/Password or LDAP authentication, the password used to authenticate the MongoDB Agent with the MongoDB deployment.

On the line listing the process, click the ellipsis icon and click Edit Storage Engine.

3

Select the storage engine. See: Storage Engine for more about choosing an appropriate storage engine for your backup.

4

Select the Sync source from which to create the new backup. In order to use the new storage engine, Ops Manager must resync the backup on the new storage engine.

5

When each snapshot starts, Ops Manager selects a replica set member to run the snapshot. This automatically selected member should have the least performance impact on the replica set. You can override the default selection.

Important

Use default selection whenever possible. This choice ensures backup availability.

On the line listing the process, click then click Select Preferred Member to Backup.

3

Click Select a member manually.

4

From the Select an available member drop-down, select the hostname and process port for the desired member.

Note

If the selected member becomes unavailable, an error message appears in the panel. Ops Manager uses a default member until the selected member is available.
