mysql-restore-s3

Warning

This will potentially put your database in a very bad state or complete destroy your data, be very careful.

Limitations

This is made to restore a backup made from mysql-backup-s3, if you backup came from somewhere else please check your format.

• Your s3 bucket must only contain backups which you wish to restore - it will always grabs the 'latest' based on unix sort with no filtering, unless exact name provided
• They must be gzip encoded text sql files
• If your bucket has more than a 1000 files the latest may not be restore, only one s3 ls command is made
