Method: Aws::Ec2#try_create_snapshot

Defined in:
lib/ec2/ec2.rb

#try_create_snapshot(volume_id, connect_timeout = nil, read_timeout = nil) ⇒ Object

Create a snapshot of specified volume, but with the normal retry algorithms disabled. This method will return immediately upon error. The user can specify connect and read timeouts (in s) for the connection to AWS. If the user does not specify timeouts, try_create_snapshot uses the default values in Rightscale::HttpConnection.
