System structure
To create images, the systems involved in the creation process must meet certain requirements. Depending on where the data that you want to store is located (in other words, on a computer of an operating system that supports octoplant or on a computer of an operating system that does not support octoplant), and where you want to store the disk images you create (in other words, in a server archive against external storage), these requirements can vary.
The following section provides you with use cases and associated processes:
Scenario 1: The data to be backed up is located on a computer, the operating system of which is supported by octoplant. The disk images have to be stored on an external network drive.
System requirements for creating disk images:
- Server with octoplant
- Target system (the computer on which the data is located) with upload agent
- External network drive
- Licensed version of Drive Snapshot in server scripting directory
- The user, who generates the disk image, has to have all necessary rights on the target system and on the remote network share
Basic steps for creating a disk image:
Step 1:
- The agent synchronises the data between the target system and the server. In doing so, Drive Snapshot is transferred onto the target system.
- The agent on the target system receives the job information from the server.
Step 2:
- The agent creates a connection to the external network drive, using the information taken from the job.
- The agent runs Drive Snapshot using the Drive Snapshot options specified in job configuration.
- Drive Snapshot creates a disk image on the external network drive.
Step 3:
- After a disk image is successfully created, the agent copies the LOG file to the server as a backup (precise storage location in server archive: BACKUP directory of the component for which the job was created).
- The path used to access to disk image (with the file manager) is the path in the LOG file.

Scenario 2: The data to be backed up is located on a computer, the operating system of which is not supported by octoplant. The disk images have to be stored on an external network drive.
System requirements for creating disk images:
- Server with octoplant
- Computer with upload agent
- Target system (the computer on which the data is located) with the data that you wish to backup (this computer has to be a different computer from the one on which the upload agent is installed)
- External network drive
- Licensed version of Drive Snapshot in server scripting directory
- PsExec in server scripting directory
- The user who generates the disk image has to have all necessary rights on the target system and on the remote network share
- The external network drive is accessible to both the agent computer and the target system
Basic steps for creating a disk image:
Step 1:
- The agent synchronises the data between the agent computer and the server. By doing this, Drive Snapshot and PsExec are transferred onto the target system.
- The agent receives the job information from the server.
Step 2:
- The agent creates a connection to the external network drive, using the information taken from the job.
-
The agent connects to the target system and copies Drive Snapshot to the target system.
- The agent runs Drive Snapshot on the target system using the Drive Snapshot options specified in job configuration.
- Drive Snapshot creates a disk image on the external network drive.
Step 3:
- After a disk image is successfully created, the agent copies the LOG file to the server as a backup (precise storage location in server archive: BACKUP directory of the component for which the job was created).
- The path used to access to disk image (with the file manager) is the path in the LOG file.
-
The agent then deletes Drive Snapshot from the target system.

Scenario 3: The data to be backed up is located on a computer, the operating system of which is supported by octoplant. The image has to be stored in the server archive.
System requirements for creating disk images:
- Server with octoplant installed
- Target system with upload agent
- Licensed version of Drive Snapshot in server scripting directory
- The user who generates the disk image requires all necessary rights on the target system
Basic steps for creating a disk image:
Step 1:
- The agent synchronises the data between the target system and the server. In doing so, Drive Snapshot is transferred onto the target system.
- The agent on the target system receives the job information from the server.
Step 2:
- The agent runs Drive Snapshot using the Drive Snapshot options specified in job configuration.
- Drive Snapshot creates the image on the target system.
Step 3:
- After the disk image is successfully created, the disk image is copied to the server as a backup (precise storage location in server archive: BACKUP directory of the component for which the job was created).

Scenario 4: The data to be backed up is located on a computer, the operating system of which is not supported by octoplant. The image has to be stored in the server archive.
System requirements for creating disk images:
- Server with octoplant installed
- Computer with upload agent
- Target system with the data that you wish to backup (Note: this computer has to be a different computer from the one on which the upload agent is installed)
- Licensed version of Drive Snapshot in server scripting directory
- PsExec in server scripting directory
- The user who generates the disk image requires all necessary rights on the target system
Basic steps for creating a disk image:
Step 1:
- The agent synchronises the data between the agent computer and the server. By doing this, Drive Snapshot and PsExec are transferred onto the target system.
- The agent receives the job information from the server.
Step 2:
-
The agent connects to the target system and copies Drive Snapshot to the target system.
- The agent runs Drive Snapshot on the target system, using the Drive Snapshot options specified in job configuration.
- Drive Snapshot creates the image on the target system.
Step 3:
- After the disk image is successfully created, the disk image is copied to the server as a backup (precise storage location in server archive: BACKUP directory of the component for which the job was created).
-
The agent then deletes Drive Snapshot from the target system.
