# Make a logical backup

--8<-- "prepare-backup.md"

## Procedure

!!! warning

    Sharded time series collections are not supported. If you use them in your deployment, you won't be able to make a backup. 
 

To make a backup, run the following command:

```bash
pbm backup --type=logical
```
     
Logical backup is the default one so you can bypass the `--type` flag. 

During *logical* backups, Percona Backup for MongoDB copies the actual data to the backup storage.

Starting with version 2.0.0, Percona Backup for MongoDB stores data in the new multi-file format where each collection has a separate file. The oplog is stored for all namespaces regardless whether this is a full or selective backup.

Multi-format is now the default data format since it allows [selective restore](restore-selective.md). Note, however, that you can make only full restores from backups made with earlier versions of Percona Backup for MongoDB.
