Configure Disk Image Backup Schedule
Image Backup and Restore feature is an effective solution to recover data against system crashes and to recreate a system similar to the old one in its entirety. This page enables the user to configure disk image backup schedules. uses VSS (volume shadow snapshot) to take image backup of the entire disk or specific partitions. It dumps the disk data into a file of format VHD ( Microsoft Hyper-v Vitural Harddisk format )locally and then uploads the dumped file to the selected Backup Server. The backed up image can be either restored to the same machine during disaster recovery or to a different machine on similar hardware or if the Backup is configured without Encryption and Compression enabled, the same image can be mounted and booted up as a virtual machine in the supported virtualization environment that includes Microsoft Hyper-V, Virtual PC, Virtual Server and Oracle Virtual Box.
In Advanced Image Backup option, the backed up VHD image even if it is compressed and encrypted can be converted into a virtual Hyper-V or VMWare image to boot up the machine as a virtual machine to quickly recovery when the new hardware for the crashed machine is not yet ready.
The restore process for these image backups are explained in this document.

Advanced Image Backup Driver Installation
Advanced Image Backup requires an one-time image backup driver installation in this machine before the first backup can be run. This driver keeps track of the changes written to the disk. If the driver is not already installed, the Add Advanced Image Backup page will not list the disks for image backup. Instead it will provide a link to click to initiate the driver installation. Once the link is clicked, the driver installation will automatically start. Once the driver installation is complete, the machine will be rebooted.
NOTE: Installation of the driver will reboot the machine. Make sure all other applications are saved before installing the driver.
Configure Disk Image Backup Schedule
Step 1: Schedule Name
The first step in configuring a backup is to give a name for the backup schedule. The backup schedule name will uniquely identify the backup. While restoring your backup data, you need to choose the data to be restored using its schedule name.
Step 2: Select Drive(s)
On the left side of the "Add Disk Image Backup" Page, is the tree with a list of disks/drives available in the client machine. You can either select the entire disks for backup or their individual partitions.
Assign Mount Point
Advance Backup assigns mount point to the volumes that do not have volume mount point or drive letter assigned. This is required as the volume without mount point cannot be scheduled for incremental backup.
Select Disk/Volume for Backup
Selecting disk or volume for Backup, checks if all the volumes have their respective drive letters assigned to it.
Auto Assign Mount Point
If any of the volumes in the Select Drive(s) list doesn't have a mount point or drive letter assigned, prompts to auto assign mount point to the drive letter.
Select Drive(s) Refreshes
On choosing to auto assign mount point, drive letter is assigned to the volumes.
Step 3: Set Basic Configuration
Same Machine - When bandwidth is low while transfering data from the client to the backup server,it might take significant amount of time to transfer all the data to a remote backup server over WAN/Internet. You can take the backup to a local external drive connected to the client machine and then physically move the external drive to the backup server location to migrate the data into the backup server. In such cases, you can select the backup type to be 'Same Machine'. Once the data is migrated to the backup server using the Server Side Seed Backup Migration, you will have to perform Seed Backup Migration (under Backup -> Seed Backup Migration) in the client machine to make it to run its backups to the remote server directly thereafter.
Local Backup location: Enter the location/directory path where the backup is to be stored in the same machine. This location should be accessible to process and should have enough free disk space for the backup data. You can copy data from this location to the backup server as seed backup data.
Select Backup Server : For running local backups of disk images, this client has to first connect to a backup server. Please select a backup server.
Remote Server - Select this option if you want the backup data to be transferred to a backup server directly when the backup schedule runs.
Select Backup Server :
This is the list of peers/backup servers in which the backup data can be stored. Once the backup server is selected, you cannot change the server name. In case the backup server name or IP address is to be changed in future, you can change it from the Seed Backup Migration page. The client will run the backup to the selected backup server.
Test connectivity - Before you select the backup server for this backup schedule, you can check the connectivity to backup server. It also checks the different settings configured in the backup server for this client and confirms if this client can backup to the chosen backup server or not.
Add Backup Server - If you don't see a particular backup server listed, you need to first add it by following this link before you can select it for this backup schedule.
Also Keep Data Locally - If you choose to backup in a remote server you can have this option enabled to have a copy in the local machine.
Temporary location for backup dumps
Enter the location/directory path where the Disk Image backup dumps are to be stored temporarily before uploading them to the backup server. Ensure that there is enough disk space in the configured temporary dump location. The backup dumps stored in the temporary location will be deleted once they are transferred successfully to remote backup server.
Size of the dump location could be huge
Disk Image backup is typically huge. The size of the backup depends on the data present in the drive been backed up. The size of each full image backup could easily be several GBs in size. Therefore, make sure the dump location specified has sufficient free space. Also once the backup is configured, you cannot change the dump location later on. Therefore make sure you specify the right dump location while configuring the backup schedule itself.
The dump location can also be a mapped/external drive. To specify a UNC path as dump location, first map the UNC path through the Mapped Drive Settings and then give the mapped drive letter as dump location. Once the backup is configured, you cannot change the dump location later on.
NOTE: Advanced Disk Image validates the dump location and local backup location with the selected source for enough free space for backup to complete.
If compression is enabled, data will be compressed in the client before it is uploaded into the backup server.
Enable - Compresses the data to the maximum. It might reduce the rate at which the client can send data to the backup server but it might save significant bandwidth and time when the data is backed up to a remote server over a WAN/Internet with limited bandwidth speed. Also, this saves disk space in the backup server.
No Compression: - This option is suitable (fastest) for backing up data within a local network where bandwidth is not the limitation, but occupies more space on destination machine as no compression is being done.
NOTE: In case, the backup is configured without choosing to encrypt or compress the backup image, the backup can be restored from server and can be directly booted in any Supported virtulaization environment that supports Microsoft VHD format. In case, of Local Backup Image, the backup image itself is bootable in supported virtualization environment.
Password Protect This Backup
This option is to enable or disable encryption of the data that is being backed up. uses a well known encryption algorithms, Blow fish and Triple-DES. If enabled, a password has to be specified which will be used for generating the encryption key. Encrypting data ensures that it cannot be read in the destination machine (backup server) where your backup is stored, and is especially relevant for sensitive information.
This option is to enable System Generated Encryption Key or use a Customized Encryption key for encrypting the backup data.
System Generated: The selected disk or drive backup will be encrypted using Blow fish algorithm with a 448 bit encryption key automatically generated by before been backed up. No password will be required while restoring the data.
Custom: This will enable the user to select the custom Encryption Technique, Encryption Key Size and the Encryption Key that needs to be used for encrypting the selected disk or drives. Please don't lose the customized encryption key, as the backed up data cannot be restored without this key.
Default Encryption Password: The selected files and folders will be encrypted with the Default Encryption Password as provided in the "Settings -> Advanced Options -> Default Encryption Password" page. Default Encryption Password is a convenient way to use the same password for all the backup schedules created in this client machine. It saves you from having to remember a different password for each backup set.
supports encryption using Blow fish or Triple DES. The Blow fish is a commonly used open source encryption technique which provides encryption based on the size of the encryption key length (from 64 bits to 448 bits). Higher the number of bits stronger is the encryption. Triple DES is a block cipher formed from the Data Encryption Standard (DES) cipher by using it three times, this technique is also supported by for encrypting the backup data. By default, Triple DES encryption technique is chosen.
Encryption Key Size
supports encryption using variable length (64 to 448 bits for Blow fish and 192 bits for Triple DES) keys. The key is generated using the password you provide. Basically the longer the key size you give the more difficult it is for someone to decrypt the encrypted files. For normal backup purposes the default 64 bit encryption should be good enough.
Provide a password here to generate the encryption key. If the password is forgotten the data can never be recovered as the data cannot be decrypted without this password. So, please ensure that you keep your password in a safe place.
Step 4: Scheduling (Decide When To Backup)
This field has the following options from which any one can be chosen.
Choose the time at which the backup should run daily. This will execute the backup everyday at the time you have provided. Unless you’ve selected the “Run this Backup each time restarts” option in Advanced Options, will run at the stipulated time only.
Choose the time and the day of the week the backup should run. will execute the backup every week on the particular day and time chosen. Note that you can select multiple days of the week if you wish to run the backup on multiple days of the week. Unless you’ve selected the “Run this Backup each time restarts” option in Advanced Options, will run at the stipulated time/day only.
Choose the time and day of the month the backup should run. will run the backup every month on the particular day and time chosen. will run at the stipulated time/day only.
Step 5: Additional Full Backups
Typically, you would do a full backup the first time you backup your data and thereafter only do incremental backups. However, like in a typical enterprise scenario, if you want to run full backups periodically and run the incremental backups in between two full backups you can Configure Additional Full Backup (Additional full backup schedule is mandatory to keep the incremental limited. Please configure an additional full backup for this schedule).
For Run Daily backups, the Additional Full Backup settings will allow you to configure daily/weekly/monthly additional full backups. For weekly and monthly backups, only Monthly additional full backups are possible.
Additionally you can specify the maximum number of full backups that need to be stored in the server. For example if you configured a weekly backup and additionally if you configure a monthly full backup, then will take a full backup the first time and then weekly do an incremental backup. The next month, will do a new full backup and subsequently run the weekly incremental backup over this full backup. After 6 months you will have 6 separate full backups in the backup server along with weekly incremental versions under each of the 6 full backups. If you have configured to store only 6 full backups "Store maximum of 6 full backups" here. On the 7th month, , after finishing the 7th full backup, will delete the first full backup along with its weekly incremental backups thus retaining always the last 6 month backups.
NOTE: The Default full-backup to store is 2
Advanced Options (Optional)
If you want to configure some additional advanced options - like, CPU utilization, Compression settings, etc. click on the Advanced Options button.
Advanced Backup Schedule Settings
There are four options here on how the backup should be scheduled.
Run this backup each time restarts - If you enable this option by checking the check box, then this backup schedule will be run every time is restarted or the machine is rebooted irrespective of the actual schedule time of this backup schedule. This is to ensure that any modified or new files created when was down are backed up as soon as possible.
Run this backup immediately after saving this configuration (thereafter, Backups will be scheduled as per the schedule stipulated) - If you enable this option, then this backup schedule will be executed once immediately after you save this backup schedule – even if it's not yet ‘time’ as per the schedule. For example if you configure a daily backup at 10.00 AM but you configured the backup at 8.00 AM, then the backup schedule will be run once immediately (8.00 AM) and then as per schedule (e.g. daily at 10.00 AM).
Attempt to run this backup every 5 minutes in case of non completion because of a problem (Network error etc.) - If enabled, the user can choose to reschedule this backup every 5/10/15/20/25/30 minutes, whenever an attempted backup is incomplete because of a network error, server crash etc. The number of times the backup will be rescheduled (due to an error) can be configured to be in between 1-5 or unlimited, with the default setting as 5. This is to ensure that an incomplete backup is completed as soon as possible without waiting for the next actual schedule time. Note that this option is enabled by default.
Data Integrity Check - supports data integrity check where the data sent from the client machine is verified for integrity at the backup server. When a file's integrity check fails, flags that file as skipped and the file is then again backed up during the next backup schedule.
Other Backup Settings
Set CPU Utilization
For each backup schedule, you can also specify the CPU utilization level as Low, Medium or High. When you set the CPU Utilization to high, the backup will be really fast - but the backup process may affect the speed of other active applications. If CPU utilization is set to Low, the backup will take longer but will be done in a non-intrusive manner allowing you to comfortably work on the computer as the backup continues in the background. In general for a continuous backup, it is best to set the CPU utilization to Medium or Low. For backups which are done every day or every week in ‘off-hours’, the CPU utilization can be set to High. Actual performance is obviously a function of your individual machine and your network. We encourage you to experiment with different settings to figure what works best for you.
Saving the configured backup
Once all the drives to be backed up are chosen and the configuration options are set, you simply need to click on the "Configure/Save Backup” button to activate the backup as per the schedule- on to the configured backup servers.
VSS services should be enabled for image backups.
Incremental backup will fail or the particular volume will be skipped if the configured volume does not have mount-point(drive letter).
Advanced Disk Image does not support Dynamic Disks. Only Dynamic Volumes are supported. Also Disks and Volumes with GPT partition table are not supported. Such unsupported disks and volumes are greyed out and cannot be configured for backup.
Currently you can seed the local data to the remote server only. After performing the seed migration, you can continue this backup schedule only to the remote server, not to both remote server and same machine.
