I would like to ask mongodb hot backup refers to: Do you use mongodump and other operations? What about cold backups?
Simple way:
1. Shut down the database, or lock the database as follows:
db.fsyncLock();
2. copy DB file/log file etc. in the backup data directory with cp instruction in the operating system.
For a variety of options/detailed procedures, please refer to the documentation on the official website:
https://docs.mongodb.com/manu …
For reference.
Love MongoDB！ Have fun！
