Operation Manual

 Custom

Specify schedules for full, differential, and incremental backups.

Differential backup is not available when backing up SQL data, Exchange data, or system state.

Additional scheduling options

With any destination, you can do the following:

 Set a date range for when the schedule is effective. Select the Run backup plan within a date

range check box, and then specify the date range.

 Disable the schedule. While the schedule is disabled, the retention rules are not applied unless a

backup is started manually.

 Introduce a delay from the scheduled time. The delay value for each machine is selected

randomly and ranges from zero to the maximum value you specify. You may want to use this

setting when backing up multiple machines to a network location, to avoid excessive network

load.

Click the gear icon, then Backup options > Schedule. Select the Distribute backup start times

within a time window check box, and then specify the maximum delay. The delay value for each

machine is determined when the backup plan is applied to the machine and remains the same

until you edit the backup plan and change the maximum delay value.

Note This option is enabled by default, with the maximum delay set to 30 minutes.

2.8.5 Retention rules

1. Click How long to keep.

2. In Cleanup, choose one of the following:

 By backup age (default)

Specify how long to keep backups created by the backup plan. By default, the retention rules

are specified for each backup set (p. 56) separately. If you want to use a single rule for all

backups, click Switch to single rule for all backup sets.

 By number of backups

Specify the maximum number of backups to keep.

 Keep backups indefinitely

Note A backup stored in a local or network folder cannot be deleted if it has dependent backups that are not

subject to deletion. Such backup chains are deleted only when the lifetime of all their backups expires. This

requires extra space for storing backups whose deletion is postponed. Also, the backup age and number of

backups may exceed the values you specify.

2.8.6 Replication

If you enable backup replication, each backup will be copied to a second location immediately after

creation. If earlier backups were not replicated (for example, the network connection was lost), the

software also replicates all of the backups that appeared after the last successful replication.

Replicated backups do not depend on the backups remaining in the original location and vice versa.

You can recover data from any backup, without access to other locations.
