Migration and upgrade

Well on my side, gitted wiki looks like collection of files corresponding to pages in old wiki. For example I have the latest version of RoboRumble Participants in the rumbles. I can either send them to you as patches, or as final verison of pages changed since your backup time.

I can even try to push them into the wiki, but the authorship will not be preserved.

How large is daily backups? I would love to provide some redundancy.

So you have the raw wikitext? Let's hold off a little longer - if we get the original that would be ideal of course, but this is good to have as an alternative. Maybe a few key pages should be updated ASAP - rumbles for example. And if we don't get the originals back, then I'm not too concerned about authorship - the wiki already went through a migration once.

Daily backups are ~250MB. I have daily for a week, then weekly for a month, then monthly. So total will be under 10GB for a long time. Extra backups can't hurt :-)

Yes. I have raw wikitexts. They also come with authorship, but I guess there is no way to stick it back.

Ok. I can manage 10GB. No problem. Though, it is sounds very wasteful for a few kB of text files changed weekly.

I don't know if there is an easy way to get diffs - it must be possible for mysql slave mirrors, but the wiki is small so we can be lazy with our backup mechanisms ;-)

I've been using mysql slaves for years, and it is not only easy to set up, but also a perfect candidate as a readonly mirror of the wiki.

And the slave can be set as master anytime, making the mirror the main wiki when the original one goes down. This ensures zero downtime if set up automatically.

Anyway, this is not a replacement of monthly backup. If a hacker managed to run drop db, the slave will also be destroyed.

And mysql slave is yes perfectly incremental.

I've set up this several times, maybe I can help setting this up. I'm also willing to help hosting readonly version ;)
