Ultimate access to all questions.
A company seeks a disaster recovery solution for its primary on-premises file storage, mounted via iSCSI, containing hundreds of TB of data. The solution must ensure uninterrupted, latency-free access for end users and minimal changes to existing infrastructure.
A
Deploy an Amazon S3 File Gateway VM on-premises with a 10 TB local cache, adjust applications for NFS access, and use EC2 for S3 bucket mounting in a disaster scenario.
B
Utilize an AWS Storage Gateway tape gateway for data backup to a virtual tape library, with nightly backups post-initial backup, and EC2 for data restoration to Amazon EBS in case of disaster.
C
Implement an AWS Storage Gateway Volume Gateway cached volume with a 10 TB local cache, iSCSI mount to the file server, file transfer, and scheduled snapshots. For disaster recovery, snapshot restoration to an Amazon EBS volume attached to an EC2 instance.
D
Set up an AWS Storage Gateway Volume Gateway stored volume matching the existing storage size, iSCSI mount and file transfer to it, and enable snapshot scheduling. In a disaster, restore from a snapshot to an Amazon EBS volume for EC2 attachment.
