| Q2:Tell us about the unique features ActiveImage Protector can provide and what are the advantages over others on the market? ActiveImage Protector provides unique and advanced features such as Inline Data Deduplication Compression built in every edition, A.I.R. enabling to restore backup image files to virtual / physical machine on a different server and hardware, SHR (Seamless Hot Restore for Hyper-V environment) and ReZoom. Linux edition now provides easy-to-use GUI enabling many of the user controls and options for making full use of ActiveImage Protector. Compared to others on the market, ActiveImage Protector is faster in backup processing, efficiently eliminates duplicate data and compresses image files at high compression rate so that backup storage needs can be reduced significantly without a need of purchasing dedicated storage options. NetJapan Inc., as in-house developed ActiveImage Protector, provides technical support including customization of the products to meet requirements from users and user-friendly detailed support services. |

| Q3:What is Inline Data Deduplication Compression built in ActiveImage Protector? Inline Data Deduplication Compression feature efficiently eliminates duplicate data blocks during the backup process without a need for purchasing an optional add-on program or dedicated storage options that provide deduplication feature, not only that, no need to do any extra configuration settings or operations. The use of ActiveImage Protector enables users to efficiently eliminate duplicate data and compress image files at high compression ratio so that backup storage needs can be reduced significantly. Also, ActiveImage Protector can complete image file compression within practical process time. For example, assuming that about 1TB (1024GB) is used for virtual environment on Windows 2008 R2 physical machine, the backup volume can be compressed to almost half of original using ActiveImage Protector. For your reference, the backup / restore process speeds are compared in the following table (tested in December, 2013):  |
||||||||||||
| Q4: How backup / restore process time differ in case Deduplication feature is used compared to the case Deduplication feature is not used? They should differ depending on the size of data in backup source. Referring to the above table in Q3, our test results indicate that backup / restore process time using Deduplication feature is 20% - 40% longer than backup / restore process time with standard compression. |
||||||||||||
| Q5: What is ReZoom feature built in ActiveImage Protector for Hyper-V? The use of ReZoom function enables you to restore VMs respectively selected from backup image of entire Hyper-V host to the same or a different Hyper-V server. The restored VM may be booted up only after restore process completes, however, multiple VM’s may be selected to collectively restore at a time |
||||||||||||
| Q6: What is SHR (Seamless Hot Restore) built in ActiveImage Protector for Hyper-V? SHR feature can quickly start-up a VM from an image backup during the restore of the VM. SHR starts a VM as a seamless virtual machine, while simultaneously restoring the same VM into Hyper-V server instead of waiting for completion of restore process. While running a seamless virtual machine directly from the backup image, restoration of the virtual machines is performed in background by using ReZoom function. In the meantime changes can be made on the virtual disk of the running seamless virtual machine. Once the restore process has completed, SHR transitions the system operation to the fully restored virtual machine. SHR provides near-zero downtime and unparalleled protection of mission critical virtual environments since not only the changes on the seamless virtual machine but also the settings including memory are transitioned to allow seamless and continuous operation. |

||||||||||||
| Q20: What is a merit / demerit of cold backup? 1. Merit of cold backup Without installing the program, it enables to create a backup image of the clean system. Since cold backup is performed while Windows system is shut down, the system resource can be used solely for reliable backup processing. 2. Demerit of cold backup Cold backup cannot be scheduled. Since Windows system has to be shut down, cold backup cannot be performed in continuous operation system. |
||||||||||||
| Q21: How long does backup process take if backup image files are stored in network storage? To get a rough idea, gigabit network should provide us with data transfer speed of 60MB/sec. Backup of 200GB data is estimated to take about 50 minutes. For the test results of backup process speed, please refer to the table in above Q3. |
||||||||||||
| Q22:If the computer is powered off when backup task is scheduled, what will happen with the scheduled task? The schedule will be skipped to run the task at the next schedule. |
||||||||||||
| Q23: How do you calculate required space in the destination storage to save image files? Required space is estimated at the minimum as follows: “Space required for one generation set” x (the number of generation sets to keep + 1) |
||||||||||||
| Q24:What is the maximum number of generations you can specify to keep with retention policy? Up to 20 "Generation sets" (a single baseline backup + the incremental backup images) can be managed. |

The backup volume can be restored to the original size or can be expanded to utilize the larger available disk space. If restoring to a smaller drive, the target disk requires at minimum the total amount of space for the actual data from the backup. |
||||||||||||
| Q32: Can ActiveImage Protector take incremental backups without creating a schedule? No. The Incremental backup feature is one of the configuration options in the schedule setup. |
||||||||||||
| Q33: Does ActiveImage Protector support VSS? ActiveImage Protector supports live backup of the Hyper-V host and guests on Windows Server 2008 R2 and Server 2012/2012 R2. On virtual machines where Microsoft Exchange Server or SQL Server supporting the VSS Writer, a snapshot of the OS on the virtual machines is taken to maintain the consistency of the data through the use of the VSS Writer. If the guest OS does not support Microsoft Volume Shadow Copy (Windows 2000 or Linux), or if the OS supports VSS-aware snapshots, the guest OS is automatically placed in a paused state from the moment the live backup starts on the host to the moment the snapshot process is complete. Once completed, the guest OS is automatically released from the paused state and is placed into the previous pre-snapshot state. |
