Different features of XWiki like the attachment store save data in a blob store. By default, this data is saved in the file system under the permanent directory. The blob store can be configured with the following properties in xwiki.proprties:
| Name | Description |
|---|---|
| store.blobStoreType | The type of the blob store to be used. Only the default "filesystem" store is bundled, "s3" is provided as an installable extension. Further implementations could be provided by extensions. |
| store.blobMigrationStoreType | The type of the blob store to migrate data from. When data is missing in the configured blob store, a migration from this blob store is attempted. This can be used to migrate data from file system to s3 or back. |
Individual blob store implementations may expose additional configuration options, see, e.g., how-to configure the S3 blob store.
