- You can have multiple backup series in the same location although the feature

still works if you set up a unique location for each series.

The `export_backup` tool lets you convert a binary backup into an exported folder.

If you need to upgrade between two major Dgraph versions that have incompatible changes,

you can use the `export_backup` tool to apply changes (either to the exported `.rdf` file or to the schema file),

and then import back the dataset into the new Dgraph version.

An example of this use-case would be to migrate existing schemas from Dgraph v1.0 to Dgraph v20.11.

You need to update the schema file from an export so all predicates of type `uid` are changed to `[uid]`.

Then use the updated schema when loading data into Dgraph v1.1.

For example, for the following schema:

becomes

Since you have to do a modification to the schema itself, you need an export.

You can use the `export_backup` tool to convert your binary backup into an export folder.

A Binary Backup directory has the following structure:

An Export directory has the following structure:

If you want to do the changes cited above, you need to edit the `g01.schema.gz` file.

With the `export_backup` tool you get the speed benefit from the binary backups, which are faster than regular exports.

So if you have a big dataset, you don't need to wait a long time until an export is completed.

Instead, just take a binary backup and convert it to an export only when needed.

Ensure that you have created a binary backup. The directory tree of a binary backup usually looks like this:

Then run the following command:

dgraph export_backup -l <location-of-your-binary-backup> -d <destination-of-the-export-dir>

Once completed you will find your export folder (in this case `dgraph.r9.u0108.1621`).

The tree of the directory should look like this:

Encrypted backups are a Enterprise feature that are available from v20.03.1 and v1.2.3 and allow you to encrypt your backups and restore them. This documentation describes how to implement encryption into your binary backups.
