 ## Backporting LAVA patches
 All upstream LAVA patches could be backported by placing them in lava-master/lava-patch/
 
+## Backups / restore
+For backupping a running docker, the "backup.sh" script could be used.
+It will store boards.yaml + postgresql database backup + joboutputs.
+
+For restoring a backup, postgresql database backup + joboutputs must be copied in master backup directory before build.
+
+Example:
+./backup.sh
+This produce a backup-20180704_1206 directory
+For restoring this backup, simply cp backup-20180704_1206/* output/local/master/backup/
