How do you create a manual backup of your Redis data at a specific point in time?

Beginner

Answer

You use the SAVE command to synchronously create an RDB snapshot file, or the BGSAVE command to create the same snapshot in the background without blocking other operations, and then copy that resulting RDB file to a safe backup location such as another server or cloud storage.
BGSAVE
-- Wait for it to complete, then copy the resulting file
cp /var/lib/redis/dump.rdb /backups/redis_backup_20260907.rdb
Real-world example A team schedules a nightly BGSAVE followed by copying the resulting RDB file to an off site cloud storage location, ensuring they always have a recent, safely stored backup available if disaster strikes.
