Active@ Disk Image
Active@ Disk Image is a disk image software that makes an exact copy of any PC disk (HDD, SSD, USB, CD, DVD, Blu-ray etc.) and stores it into a folder. The disk images may be used for backups, PC upgrades or disk duplication purposes. In case of computer failure, a backup image may be used to recover your computer system or find & restore any necessary files from within an image. Create & Restore Disk Image Backup (occupied clusters only). Image Compression (Fast, Normal and High). Mounting images as virtual drives. Incremental and Differential images. RAID is supported. Rescue bootable media. Create & restore raw disk image (sector by sector copy). Scheduled backups. Windows Servers are supported. Image Encrypting (AES-128, AES-192, AES-256). Scripting support. E-mail notifications. Cloud storage.

Google Cloud Persistent Disk
Reliable, high-performance block storage for virtual machine instances. HDD offers low-cost storage when bulk throughput is of primary importance. SSD offers consistently high performance for both random-access workloads and bulk throughput. Both types can be sized up to 64 TB. With multi-reader mounting, many virtual machines can read data from a single Persistent Disk. Attaching a disk to more virtual machines does not affect aggregate performance or cost. No longer worry about undersizing your block devices. Persistent Disk gives you unlimited flexibility by allowing you to resize your storage while it’s in use by one or more virtual machines with no downtime. For maximum flexibility and minimal effort, snapshots are geo-replicated and available for restore in all regions by default. Snapshots of a block device can take place in minutes rather than hours. Persistent Disks are automatically encrypted to protect your data, in transit or at rest.

Huawei Cloud Elastic Volume Service
Elastic Volume Service (EVS) provides highly durable block storage for cloud servers such as Elastic Cloud Servers (ECS) and Bare Metal Servers (BMS). EVS offers 99.9999999% durability and as little as 1 millisecond of read/write latency for a broad range of mission-critical applications. You can choose from EVS disks with high I/O, general purpose SSD, or ultra-high I/O. Whatever your storage demands, there is always a great solution at a reasonable price, and with EVS disks you can always add space without disrupting services. If the capacity of an EVS disk is insufficient, you can immediately increase block storage space, even if the disk is currently in use. In just a few clicks, you can scale a system disk up to 1 TB and a data disk up to 32 TB, all without any disruption to your workloads. Data on EVS disks is encrypted using the industry-standard AES-256 encryption algorithm and keys.

Amazon Elastic Block Store (EBS)
Amazon Elastic Block Store (EBS) is an easy to use, high-performance, block-storage service designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction intensive workloads at any scale. A broad range of workloads, such as relational and non-relational databases, enterprise applications, containerized applications, big data analytics engines, file systems, and media workflows are widely deployed on Amazon EBS. You can choose from six different volume types to balance optimal price and performance. You can achieve single-digit-millisecond latency for high-performance database workloads such as SAP HANA or gigabyte per second throughput for large, sequential workloads such as Hadoop. You can change volume types, tune performance, or increase volume size without disrupting your critical applications, so you have cost-effective storage when you need it.
