A backup task defines which files are backed up and which data should be excluded from backup. Creating a task is the first step of the standard backup procedure. Once you created a task, create a schedule to specify when you want to back up your data. In the third step you will create a backup event by selecting where to back up your data to and how.


  1. From Main Selection -> Tasks -> By Clients, select your client and click New Backup Task. The New Backup Task window opens.
  2. Use the browse button to specify the Source and select what you want to back up. If you want to back up individual files, you can either browse for directories and files that you want to include in the backup or enter their names followed by a comma (C:/Program Files/SEPsesam/var/db,C:\Users\AA\Documents\references). Typically, if you select the source by browsing, the task type and task name are set automatically. A few special task types are rare exceptions and thus require a manual selection of the relevant type and specifying the task name.
  3. Information sign.png Note
    In case of the Windows clients Path backups, the option Backup with VSS is enabled by default. It is possible to exclude a specific VSS writer from backup or disable VSS; for details, see SEP sesam Volume Shadow Copy Service (VSS) for Windows.
  4. Optionally, specify the filenames or patterns which you do not want to back up in the Exclude list. For details on various exclude options, see Creating Exclude List.
    SEP Tip.png Tip
    If the number of files or directories you want to include for backup exceeds allowed length for task source (max. 1024 characters), you can create a separate file that contains a list of selected sources by using Additional call arguments (see step 5).
    If you want to add a comment, enter it in the Notes field.

  6. Optionally, edit the assigned Task name. You can give your task a meaningful or descriptive name (max. 15 letters) that clearly identifies it, for example diagnostix_all for a backup of your client named diagnostix.
  7. Optionally, click the Options tab if you want to specify additional backup or restore options.
    • You can enable the pre/post backup or restore commands.
    • Information sign.png Note
      To use a configurable pre/post interface, you have to activate it first and create your own commands. Interfaces can be activated in GUI: in the menu bar, click Configuration -> Interfaces -> select the interface you want to activate and the client. The interface script window opens, allowing you to configure the desired action. Once done, click Save to activate the interface. The interface is saved to the <SESAM_ROOT>/bin/sesam directory. For more details, see Configuration: Interfaces.
    • Under the Additional call arguments part, you can specify special backup or restore options by using the relevant field. For example, by specifying the following command in the Backup options field you can prevent your backups on Linux to finish with errors if a file has been changed during backup (a different file size or deletion):
    •  -o ignore_finderr=<regex>|ALL

      If you want to avoid all such errors/warnings, specify:

      -o ignore_finderr=ALL

  8. Switch to the Encryption & Compression tab if you want to set encryption or compress data.
  9. In v. ≥ 4.4.3 Beefalo V2, click the OS Access tab and specify the credentials to access the resources on the target client. If you have already specified the credentials when configuring the client or its location, select an existing credential set from the drop-down list. Otherwise, click New and enter the credentials for the target client.
  10. Use other corresponding tabs to consolidate individual tasks under a specific task group or assign a task to the schedule.

  11. Click OK to create the task.
SEP Tip.png Tip
To prepare for a possible breakdown of the SEP sesam Server and disaster recovery, you have to perform a self-backup of the SEP sesam by configuring at least one backup task with the name SESAM_BACKUP. For more details, see Preparing for Disaster Recovery.
SEP Tip.png Tip
Optionally, you can assign individual tasks to a task group and then trigger the start of all tasks belonging to that group with a single event. For details, see Adding a Task to the Task Group.
