"Savannah now has 12 mirrors covering 8 countries and 4 continents!"

couldn't they just use one of those for the recovery?

> The last backup was performed while RAID was buggy

it's likely that the mirrors were also then sync'ed from the buggy RAID, and contain beautiful copies of the same crap data that's on the master. poor guys.

From the sound of it, their servers didn't just die, they first started corrupting the data, which likely resulted in the corrupted data getting mirrored to the other servers... Unfortunately, a really sucky situation to find yourself in.

Looks like case against proprietary RAID solution and not self-healing filesystem.

Or perhaps not.

More likely like a case for daily incremental backups with a long history
as no hardware or filesystem is completely secure from such failures.
There are bugs everywhere.

+ many.

12-months to 2 years of one-month granularity backups <- tape
2 months of 1-day granularity backups <- tape
1 week of twice-daily backups <- disk

much profit

Just for files released by projects, which is what is mirrored. For the rest (database, websites, source code repositories) the mirrors have no information at all.
