Recover accidentally deleted data
So you deleted a mailbox and have no backups, he?
If you noticed your mistake within a few hours, you can probably recover the users data.
SOGo¶
We automatically create daily backups (24h interval starting from running up -d) in /var/lib/docker/volumes/mailcowdockerized_sogo-userdata-backup-vol-1/_data/.
Make sure the user you want to restore exists in your mailcow. Re-create them if they are missing.
Copy the file named after the user you want to restore to __MAILCOW_DIRECTORY__/data/conf/sogo.
1. Copy the backup: cp /var/lib/docker/volumes/mailcowdockerized_sogo-userdata-backup-vol-1/_data/restoreme@example.org __MAILCOW_DIRECTORY__/data/conf/sogo
2. Run docker-compose exec -u sogo sogo-mailcow sogo-tool restore -F ALL /etc/sogo restoreme@example.org
Run sogo-tool without parameters to check for possible restore options.
3. Delete the copied backup by running rm __MAILCOW_DIRECTORY__/data/conf/sogo
4. Restart SOGo and Memcached: docker-compose restart sogo-mailcow memcached-mailcow
Mail¶
In case of an accidental deletion of a mailbox, you will be able to recover for (by default) 5 days. This depends on the MAILDIR_GC_TIME parameter in mailcow.conf.
A deleted mailbox is copied in its encrypted form to /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/_garbage.
The folder inside _garbage follows the structure [timestamp]_[domain_sanitized][user_sanitized], for example 1629109708_exampleorgtest in case of test@example.org deleted on 1629109708.
To restore make sure you are actually restoring to the same mailcow it was deleted from or you use the same encryption keys in crypt-vol-1.
Make sure the user you want to restore exists in your mailcow. Re-create them if they are missing.
Copy the folders from /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/_garbage/[timestamp]_[domain_sanitized][user_sanitized] back to /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/[domain]/[user] and resync the folder and recalc the quota:
docker-compose exec dovecot-mailcow doveadm force-resync -u restoreme@example.net '*'
docker-compose exec dovecot-mailcow doveadm quota recalc -u restoreme@example.net
