Seems this require something like PITR
Anyway this requires capture the "binlog" and keeping the logs between version 🤔 If you want you can trying to duplicate the logs for cluster and add this feature

You can use BGSAVE to backup all your data.
Also you can set the BGSAVE scheduler `bgsave-cron` in config file to setup regular backup.

No database allows you to (globally) backtrack to any time point without any cost.
It will come with huge storage expenses.

Beside, the bgsave is also important here since keeping the cluster log is very expansive, so some syntax need to be well-design for this scenerio.

No database allows you to backtrack to any time point without any cost.
It will come with huge expenses and is impractical.

@Aneuuu Thank you for starting a discussion. Could you please elaborate on the topic? As far as I know, Redis supports making snapshots and restoring the state from the snapshots. Do you mean something else?
