Can I restore a Redis key when overwrite it by RENAME command

I made a horrible mistake by using the command RENAME key1 key2. The data in key2 was completely wiped out. Is there anyway to restore the data that was stored in key2?

Solution

Unless you don't have a dump'ed value of key2, key2's data is gone. If you have the dumped value, then you can restore it by RESTORE command.

RESTORE key2 0 "<dumped value.>"
