Abstract

The embodiment of the invention discloses a backup method and device for an MongoDB database, a recovery method and device for the MongoDB database, electronic equipment and a storage medium. The backup method comprises the following steps: acquiring a first timestamp; sequentially pulling a plurality of database operation logs from the MongoDB database by taking the first timestamp as starting time; classifying the plurality of pulled database operation logs to obtain a data definition language operation log and a data manipulation language operation log; wherein the data definition languageoperation log is used for recording changes of a data structure corresponding to the MongoDB database, and the data manipulation language operation log is used for recording changes of data corresponding to the MongoDB database; and sequentially writing the data definition language operation log into the first temporary file to generate a first file, and sequentially writing the data manipulationlanguage operation log and the data definition language operation log into the second temporary file to generate a second file. According to the embodiment of the invention, the incremental data backup of the MongoDB database can be quickly written into the file, so that the storage space required by data backup is reduced.

Description

technical field [0001] The invention relates to the technical field of cloud services, in particular to a method, device, electronic equipment and storage medium for backing up and restoring a MongoDB database. Background technique [0002] MongoDB is a database based on distributed file storage. It is a product between relational databases and non-relational databases, and can store more complex data types. For the MongoDB database, MongoDB data is the core, so data security and easy migration are also critical. At present, there is physical backup support for MongoDB full data backup, that is, the entire folder of MongoDB data can be copied. However, the technical solutions for the backup and recovery or migration of MongoDB incremental data have not been particularly ideal. However, full backups require more storage space. Due to the limited storage capacity of the internal database operation log (Oplog) of the MongoDB database, it is urgent to propose a technical means...
