How make a brick-level backup
The Zarafa commercial editions also include a brick level backup. Using this backup tool, you can create a backup for individual mailboxes. With this backup you can restore a single item, folder or mailbox.
The Zarafa Brick level backup contains two tools:
zarafa-backup zarafa-restore
Creating a brick level backup
zarafa-backup -u username
With the -a option you can create a backup for all users and the public folder. See the man page for more options of the zarafa-backup tool.
The zarafa-backup tool will create two files in the current directory:
username.index.zbk username.data.zbk
The data file contains all items of the mailbox of the user (including all attachments). The index file is a text file which contains all information about the items, like the subject, received date and other information.
If you run the backup tool a second time, the backup tool will do an incremental backup of only the latest/changed items. The incremental file will get the name username.data.zbk.1.
The index file will be extended with the latest changes.
Restoring a item of folder
To restore a single item or folder you need to have the restore key of the item. In the directory /usr/share/zarafa/zarafa-backup-helpers/ there is a script called readable-index.pl.
This script will show the index file in a userfriendly view, so you can select the restore key on an item.
readable-index.pl username.index.zbk | less
The first column of this view is the restorekey. This restorekey is used to restore and item or folder.
To restore an items to the original location, run:
zarafa-restore -u <username> <restorekey>
If you want to restore a complete folder, you need to select the restore key of a folder and restore it with the following command:
zarafa-restore -r -u username restorekey
Full mailbox restore
To restore a complete mailbox, there is a full-restore script available in the directory /usr/share/zarafa/zarafa-backup-helpers.
To restore the full mailbox, execute:
full-restore <user> <newuser>
