 NOTE that much of this page is specific to FV 0.8.13 and later.
+
+== Backups ==
+
+We recommend backing up your !FlowVisor database, which includes both configuration information and non-transient FV state (FV slices, flowspace rules, etc).
+
+=== Backup ===
+
+There's an fvctl command that saves a JSON version of the DB:
+
+{{{
+fvctl --passwd-file=/etc/flowvisor.passwd dumpConfig config.json
+}}}
+
+You can then back up this file however you back up other plain files at your site.
+
+=== Restore ===
+
+NOTE that fvconfig can only be run when FlowVisor is '''not running'''.
+
+NOTE that this completely and irrevocably overwrites your existing FlowVisor database! Use with caution.
+
+You need to run the restore as the 'flowvisor' user, since that user has the right permissions to create the DB files:
+
+{{{
+sudo -u flowvisor fvconfig load config.json
+}}}
+
+The last argument is the input file to use, and can be any file name as long as it's readable by the 'flowvisor' user.
+
+This is generally sufficient, but if your database is in a very bad state, you may need to delete it completely and re-create it before you can load the JSON file:
+
+{{{
+sudo rm -rf /usr/share/db/flowvisor/FlowVisorDB
+sudo -u flowvisor fvconfig generate /dev/null
+sudo -u flowvisor fvconfig load config.json
+}}}
+
+In that second step, just hit return when prompted for a password (this will be overwritten by the next step); and ignore the "keytool error" error, it's just telling you that you already have a key pair.
