 In this version you can backup with cli or with the web admin. The cli way allows you to do more things. The webadmin way is more accessible.
 
-## Webadmin way
+## Web admin
 Basically with the webadmin, you can:
 
-- backup into /home/yunohost/archives/
-- choose to backup one or more things between mail data, home data, configuration and apps
-- list your backup
+- backup into `/home/yunohost/archives/`
+- choose to backup one or more data among:
+ - apps data
+ - emails
+ - home data
+ - configuration
+- list backups
 - see what there is in a backup
 - restore selectively a backup
 
-**Caution:** to do a backup, you need to have enough free disk spaces in the destination directory. For example, if you have 20GB in /home/data you need to have enough space to contain this 20GB compressed in a tar.gz. To do the tar.gz, yunohost backup use shallow copy, to avoid to need more spaces to be able to create the tar.gz .

 **Caution:** If you use selective restore, be sure to not create discordant operation. For example, if you restore an app using a domain that have been deleted from YunoHost, you need to read the domain or to restore all configuration files.
 
 We have already planned where we will add some feature like:
 
-- backup in an other place
+- backup in an other memory device
 - download/upload a backup
 - crypt a backup
-Some feature are almost ready in webadmin, but the api is not for the moment.

 As you can see in the answer, there is 2 hooks which backup data (data_home and data_mail). By default, the mysql data aren't saved, because the apps should save themselves their databases.

 If you want modify a general conf file, you should use hooks to trigger a modification of the conf file after each call of `yunohost regenconf`.
