Si3 Replications

Replication was introduced with SEP sesam version 4.4.2. Replication tasks are managed under Main selection -> Tasks -> Si3 Replications menu. For detailed explanation on how to configure replication, its advantages and limitations, see Replication.

Here is a description of all the fields and the functions assigned to them:

Name

Enter a meaningful name for the replication task, e.g., rep-source_mediapool-to-target_mediapool.

Parameters

• Media pool
  Specification of the source media pool
• Pool
  Enter the name of the source media pool from which the data will be replicated, e.g., source_mediapool.
• Drive
  Select the drive number of the drive that will be used to read the data.
• Destination
  Specification of the target
• Pool
  Enter the name of the target media pool to which the data will be replicated, e.g., target_mediapool.

	Note
	With v. 4.4.2, the EOL (end-of-life) of the target media pool will be ignored. If a save set is deleted from the source media pool, it will also be deleted from the target media pool. It is recommended to upgrade to the latest version, which solves this issue.

• Drive
  Select the drive number of the drive that will be used to write the data.
• Interface
  Specify the network interface of the RDS through which the data transfer will be executed, e.g. the name of the RDS.
• Date
  Define the time frame of the backups that will be replicated. It is recommended that you use the option Relative backup date instead.
• Relative backup date
  Define the time frame of the backups that will be replicated by specifying appropriate values for the from/to fields. These fields specify the number of days in the past that are considered for replication, meaning all data in the source media pool that was backed up within a given period of time is going to be considered for replication to the remote pool. For example, to replicate all data from the past week, the Relative backup date is set to -7 while to is set to 0. Because the replication will always replicate only new blocks of data, you can specify a really high number in the from field, such as -99.999. This way all backups since the initial replication will always be checked, but only the changed data is going to be replicated.

	Note
	Only the save sets with status successful and with warnings are selected for replication, whilst save sets with errors and only partially restorable save sets (containing data from cancelled backups) are not replicated.

• based on
  The Sesam days option is selected by default. Sesam day is a backup day you define according to your backup routines. For example, your backups can run after midnight but retain the backup date of the prior day. Sesam day/backup day is defined by time set in the NEWDAY event. For details, see NEWDAY Event.
