alirezastack / backup_redis_rdb.sh
Last active April 24, 2024 08:11
Backup Redis RDB file - BASH Script
#!/bin/bash
#
## redis backup script
## usage
## redis-backup.sh port backup.dir
## Redis is very data backup friendly since you can copy RDB files while the database is running: the RDB is never modified once produced, and while it gets produced it uses a temporary name and is renamed into its final destination atomically using rename(2) only when the new snapshot is complete.
# Scripts & Files
