describeBackups method
Returns the description of specific Amazon FSx backups, if a
BackupIds
value is provided for that backup. Otherwise, it
returns all backups owned by your AWS account in the AWS Region of the
endpoint that you're calling.
When retrieving all backups, you can optionally specify the
MaxResults
parameter to limit the number of backups in a
response. If more backups remain, Amazon FSx returns a
NextToken
value in the response. In this case, send a later
request with the NextToken
request parameter set to the value
of NextToken
from the last response.
This action is used in an iterative process to retrieve a list of your
backups. DescribeBackups
is called first without a
NextToken
value. Then the action continues to be called with
the NextToken
parameter set to the value of the last
NextToken
value until a response has no
NextToken
.
When using this action, keep the following in mind:
-
The implementation might return fewer than
MaxResults
file system descriptions while still including aNextToken
value. -
The order of backups returned in the response of one
DescribeBackups
call and the order of backups returned across the responses of a multi-call iteration is unspecified.
May throw BadRequest. May throw FileSystemNotFound. May throw BackupNotFound. May throw InternalServerError.
Parameter backupIds
:
IDs of the backups you want to retrieve (String). This overrides any
filters. If any IDs are not found, BackupNotFound will be thrown.
Parameter filters
:
Filters structure. Supported names are file-system-id and backup-type.
Parameter maxResults
:
Maximum number of backups to return in the response (integer). This
parameter value must be greater than 0. The number of items that Amazon
FSx returns is the minimum of the MaxResults
parameter
specified in the request and the service's internal maximum number of
items per page.
Parameter nextToken
:
Opaque pagination token returned from a previous
DescribeBackups
operation (String). If a token present, the
action continues the list from where the returning call left off.
