Backup and Redis

[mbressman]

Just wondering if there is any benefit (as far as backups) to running EtherCalc without Redis vs. with Redis? It seems like without Redis, each EtherCalc spreadsheet is a separate file - but perhaps that makes restoring a corrupted spreadsheet easier (especially if they are backed up multiple times throughout the day as they are changed)? Is there a way to revert back from Redis (without losing all the stored spreadsheets already in Redis)?

Thanks!
