Using a third-party snapshot with BLM Archiver
When creating a BLM archive request, if you select the option to use a third-party snapshot, the DS-System integrates with the third-party software to create a snapshot of the required folders. Once the snapshot is created, the DS-System unlocks the backup and the BLM request is performed from the snapshot data.
If you do not select the option to use a third-party snapshot, the DS-System locks the backup for the duration of the BLM archive process.
IMPORTANT: Ensure the third-party software is installed and configured correctly, otherwise the backup will remain locked until you delete the BLM request.
If you select the option of creating a third party snapshot, DS-System integrates with the third-party software to create a snapshot of the required directories. Once the snapshot is created, DS-System unlocks the backup and the BLM request is performed from the snapshot data.
To use a third-party snapshot with BLM Archiver:
When using a third-party snapshot with the BLM Archiver, the following occurs:
• The DS-System writes a request file (sreq_n.txt) to the blm_pitc subfolder on the DS-System for the third-party software to read, where n is the request number. This file lists all the storage locations where the requested backup data is located.
• The third-party software reads the file and copies the data, and then writes a response file (sresp_n.txt) to the primary storage location in the blm_pitc subfolder on the DS-System. This file lists the image locations from where the DS-System should read the data.
NOTE: The request and response files and must be in Text File Format (UTF-8, no Unicode marker) and the order of the folders must be identical.
• The third-party software deletes the request file (sreq_n.txt). The DS-System unlocks the backup.
• The DS-System starts copying data to the BLM Archiver from the third-party snapshot location.
• When the BLM archive process is finished, the DS-System deletes the response file (sresp_n.txt).
