• Like most, I'm familiar with relational dbs so I am nervous about reddis. A while ago I read that if there's a memory problem, that tons of data would be lost. Is this true or is data stored in a file system of some sort?

    Can you backup data that's stored in reddis?

  • Redis backs up to storage at set intervals (configurable).

    For example you could have it backup every 15 minutes or every 200 times its accessed (think that's how the calls work).

    So if your sever did mysteriously crash. The most you'd lose would be whatever happened since the last save. You can use MongoDB instead which saves everything to storage. But isn't as quick in terms of read/write.

    Hope that helps.
