Übersicht

The SEP sesam online module for Kopano (formerly Zarafa) provides hot backup of Kopano groupware servers. This includes backing up and restoring single user mails, mailboxes and public folders; you can perform a simultaneous backup of multiple mailboxes as well as parallel export of mailboxes. It also enables efficient migration, deduplication and replication.

Note that SEP sesam Kopano extension does not support Kopano Community Edition since this does not include brick level backup (back up individual e-mails, contacts and calendar items for users and public folders). You can use SEP sesam Path backup to perform a file system backup of Kopano system.

For more information on Kopano editions, see Kopano content editions.

Backup levels

In addition to previously existing COPY backup level, backup levels FULL and DIFF are introduced for Kopano backup as of SEP sesam version 4.4.3 Grolar.

  • FULL: Backs up all data specified by the backup task (e.g. files), regardless of whether it has been changed or not.
  • DIFF: Saves only the data which was created or changed after the last FULL saveset had been created (of the same task). A differential backup is faster than a full backup, however, to restore the whole data source, first the saveset of the full backup has to be restored followed by restore of the DIFF saveset.
  • COPY: Backs up all data defined by the backup task, regardless of when it was last changed; note that a COPY backup (in contrast to FULL) cannot be used as a starting point for DIFF backups and restores. COPY backup is usually used for additional full backups, e.g., monthly backups, or backups for archiving, i.e., removal from storage.

For more information, see Backup Level.

Prerequisites

Adding the Kopano client to SEP sesam environment

Once you have downloaded the SEP sesam package, proceed as follows: You configure a new client by adding it to the SEP sesam environment: Main selection -> Components -> Topology -> New Client -> add your Kopano client. For details, see Configuring Clients.

Before proceeding, you should validate that you can back up to SEP sesam. Run a test Path backup manually to ensure that the backups work. For details on typical backup configuration, see Standard Backup Procedure.

Configuring the mailbox backups

Create a new backup task for the backup of the Kopano mailboxes.

  1. From Main Selection -> Tasks -> By Clients, select Kopano client and click New Backup Task. The New Backup Task window opens.
  2. Specify the Source in the following format:
    • All users and public folders: all
    • All users: all_users
    • All public folders: public
    • One or more user mailboxes (for example, mk, ryan): <User1>,<User2>
    • You can enter the backup source
      Kopano enter bck source de.jpg
      or browse for it.
      Kopano browse bck source de.jpg


    Note that if you select the source by browsing, the task type and task name are set automatically. If you enter the source manually, you have to enter the task name and select Kopano task type.

  3. Optionally, specify the mailboxes which you do not want to back up in the Exclude list. Exclude patterns are regular expressions which are compared against username. For example, ^support$ will exclude the user support and support will exclude users like support, sepsupport and support1. For details, see Creating Exclude List.

  5. Optionally, you can configure a simultaneous backup of multiple mailboxes by using the command max_exports higher than zero (0). Under the tab Options, enter the following in the Backup options (previously Save options) field: -a max_exports=<number higher than 0>. For example, to run 5 simultaneous backups, enter -a max_exports=5. This parameter forces the given count of Kopano backup processes on the Kopano server. Make sure that your Kopano server can manage running the specified number of processes at the same time.
  6. Click OK to create the task.

  7. If you want to start the newly created task immediately, right-click the name of the task and click Immediate Start. If you want to schedule the task, click New Schedule under Main Selection -> Scheduling -> Schedules. For details, see Creating a Schedule.
  8. Once you have configured a schedule, you must create a new backup event for it. Go to Main Selection -> Scheduling -> New Backup Event, click the Parameter tab and select one of the available backup levels (FULL, DIFF or COPY). For more information, see Creating a Backup Event.
