5 1 0:Kopano Backup

From SEPsesam

Welcome to the latest SEP sesam documentation version 5.1.0 Apollon. For previous documentation version(s), check documentation archive.


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 a parallel export of mailboxes. It also enables efficient migration, deduplication and replication.

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


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 -> Clients -> 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

If you prefer to watch a video rather than to read a step-by-step guide, you can learn all the steps of the procedure by watching Backup and restore of Kopano with SEP sesam.

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: <User1>,<User2>

    You can enter the backup source, or browse for it.

    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 that 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.

  4. Optionally, you can configure a simultaneous backup of multiple mailboxes by using the command max_exports in combination with a number 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. (default value for max_exports is 1)
  5. Click OK to create the task.

  6. 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.
  7. 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.
