The following example shows how to get the current status. Note: This call does not require an authentication token.

A backup copy of the Repository Services is created by starting a daemon process that will stream all of the repository to a file, and then upload the file to its S3 bucket. This daemon can be
launched and monitored from a set of HTTP Rest calls. Note: All Backup/Restore services will require an administrator's session token.

First, log-in as an administrator (use the platform@sagebase.org account) to get an administrator's session token:

Code Block


curl -i -k -H sessionToken:YourSessionToken -H Accept:application/json -H Content-Type:application/json -d '{
  "email": "<admin username>",
  "password": "<admin password>"
}' https://staging-auth.elasticbeanstalk.com/auth/v1/session

Once you have the admin token the backup daemon can be started with the following command:
Request

Code Block
curl -i -k -H sessionToken:<your admin token> -H Accept:application/json -H Content-Type:application/json -d '{ }' https://staging-reposervice.elasticbeanstalk.com/repo/v1/admin/daemon/backup

Response

	"startedBy":"platform@sagebase.org",
	"startedOn":1313707136615
}

Once the daemon is started, its progress can be monitored using its 'id' returned from the 'admin/daemon' call:

	"backupUrl":null,
	"totalTimeMS":26145,
	"startedBy":"platform@sagebase.org",
	"startedOn":1313707136615
}

In this example, we are showing that the backup failed. When there is a failure, the status will show as 'FAILED', and 'errorMessage' and 'errorDetails' should show the message and stack trace of the failure. In this example, the service IAM user did not have permission to write the backup file to S3. After fixing the AWS permissions we can try running the backup again:

	"totalTimeMS":24880,
	"startedBy":"platform@sagebase.org",
	"startedOn":1313708374613
}

This time we can see that the backup 'status'='COMPLETED', and that the 'backupUrl' is no longer null and that the entire backup ~25 seconds to complete. We can now use the file found at the 'backupUrl' to restore synapse.

Restore a Repository from a Backup Snapshot

...

Fist make sure the backup file that you want to restore is in the S3 bucket that belongs to that service. A service can only download files from its own bucket.

Once the backup in place in S3 we are ready to authenticate and get an administrator's session token:

Code Block


curl -i -k -H sessionToken:YourSessionToken -H Accept:application/json -H Content-Type:application/json -d '{
  "email": "<admin username>",
  "password": "<admin password>"
}' http://localhost:8080/services-authentication-0.6-SNAPSHOT/auth/v1/session

Now use the administrator's token to start the restore daemon. You must provide the file name of the backup file found on S3 to the daemon:
Request

Code Block


curl -i -k -H sessionToken:YourSessionToken -H Accept:application/json -H Content-Type:application/json -d '{
  "url": "BackupDaemonJob6696-911306061719227050.zip"

	"backupUrl":null,
	"totalTimeMS":0,
	"startedBy":"platform@sagebase.org",
	"startedOn":1313710288153
}

Once the daemon is started its progress can be monitored in the same way as we monitored the backup daemon, using the 'id' provided by the /admin/daemon:

	"totalTimeMS":781,
	"startedBy":"platform@sagebase.org",
	"startedOn":1313710288153
}

Just like in our backup example, the restore failed as indicated by the 'status'='FAILED'. Again it looks like the service did not have permission to download the S3 file. Upon closer inspection we find that we have a cut and paste error with the file name. Once our error is identified, we can start another restore daemon with the following results:

	"totalTimeMS":46800,
	"startedBy":"platform@sagebase.org",
	"startedOn":1313711855784
}

This time we can see that the restore 'status'='COMPLETED', and that the entire restore took ~47 seconds to complete. We have successfully migrated all data from the staging to our local repository service.

Storage Usage

Check the (external) storage usage by the Synapse system. You must be an administrator to perform these actions.

Get aggregated totals

Aggregate over any combination of dimensions listed in StorageUsageDimension except for USER_ID and ENTITY_ID which are provided via separate APIs. For the list of aggregating dimensions, see Synapse Entity Types. For example, the following command lists storage usage by content type and storage provider:

Code Block

language	bash

curl -i -H sessionToken:<token> -H Accept:application/json https://repo-staging.sagebase.org/repo/v1/admin/storageSummary?aggregation=CONTENT_TYPE,STORAGE_PROVIDER

Will get results like the following

Without any aggregation, the same URL will get only the grand totals.
