Backup and recovery

Backups protect against data loss by letting you restore data.

YDB provides multiple solutions for backup and recovery:

• Backing up data to files and restoring it using the YDB CLI.
• Backing up data to S3-compatible storage and restoring it using the YDB CLI.

YDB CLI

Files

To back up data to a file, the following commands are used:

• ydb admin cluster dump — to back up a cluster' metadata
• ydb admin database dump — to back up a database
• ydb tools dump — to back up individual schema objects or directories

To learn more about these commands, see Exporting data to the file system.

To restore data from a backup, the following commands are used:

• ydb admin cluster restore — to restore a cluster' metadata from a backup
• ydb admin database restore — to restore a database from a backup
• ydb tools restore — to restore individual schema objects or directories from a backup

To learn more about these command, see Importing data from the file system.

S3-compatible storage

To back up data to S3-compatible storage (such as AWS S3), run the ydb export s3 command. To learn more about this command, follow the link to the YDB CLI reference.

To restore data from a backup created in S3-compatible storage, run the ydb import s3 command. To learn more about this command, follow the link to the YDB CLI reference.
