mongodb hot backup and cold backup

Question

Excuse me, mongodb hot backup refers to the operation implemented using mongodump, etc.? What about cold backup?

Answer 1

Easy way:

1. Close the database, or lock the database as follows:

db.fsyncLock();

2. Use the cp command in the operating system to copy the DB file/log file, etc. in the backup data directory

For various options/detailed steps, please refer to the official website’s documentation:

For reference.
