Is there Drush command that can backup whole multisite platform:
- database dump of each site
- code of each site
- backup of sites/all or complete core with sites/all
- and all that in just ONE tar.gz
There is a archive-dump command which can backup whole platform code and database, but it does that for each site, and omitting other sites from its archive. And that is a problem because if you want to use that backup, and let's say you have 3 sites in platform, you would have to untar 3 backups of each site, and then merge those so your /sites folder has all three sites there, instead only one per archive.
Second, less annoying problem with that command is, if you provide it argument @sites, it will try to backup default site as well, which is not used on Aegir.
