Migrating a Customer to another DS-System
Backed up data can be migrated to a new DS-System. This can be done at the customer or at the DS-Client level. This feature supports cross-platform migration between DS-Systems (e.g. Windows DS-System to Linux DS-System, etc.).
- For DS-Client level migration, see "Migrating a DS-Client to another customer or DS-System"
Migration (Export/Import processes) should be planned carefully, because you should expect it to take HOURS to complete, especially if there are millions of files and multi-GBs of data.
- IMPORTANT NOTES:
- Make sure the DS-System does not reboot.
- It is VERY IMPORTANT to check for any errors at each step during migration.
- Before you export, you should run System Admin and Autonomic Healing on each DS-Client under the customer you are going to export. If errors are reported, you should fix them.
- You must verify that enough space is available for the Export and Import Processes before performing them.
- For Extensible Storage, even if there is enough physical space for the data to be imported, you must manage the logical space in each storage location. If the storage locations run out of logical space, the customer's backup processes will not be allowed.
- Before you export, deactivate all the customer's DS-Client accounts.
Export Customer
1. In the Customers Tab, browse and highlight the customer to migrate.
3. Click Export Customer. The Export Customer [...] screen appears.
- F1 Help: See "Export Customer / DS-Client [...]".
4. Enter a valid path (buffer directory) on the DS-System or DS-System network that can accommodate the full storage of the selected Customer.
- At this point, you must decide where to Export the data: on the same Extensible Storage volume of the target DS-System, or to a different volume entirely.
- If you export to a location on the same storage volume, the Import Customer process will give you the option of a faster import method.
- Note: The Overwrite Options screen appears if you are retrying the "Export Customer" process and DS-System detects that usable data exists in the export location. This can happen if the previous process was stopped or interrupted. You can choose to overwrite the data and restart from the beginning, or try to resume from the point before the first error.
5. Click Export History. The Export history for [...] screen appears.
- F1 Help: See "Export history for [...]".
6. Enter a valid path (buffer directory) on the DS-System or DS-System network to place the history (database logs) for this Customer. [These customer logs will not be imported to the new DS-Systems. Since you can choose to delete the original customer, you may wish to save these logs for historical purposes.]
- Note: For UNIX DS-Systems, you must use a mounted point.
Import Customer
You can import the customer data to the target DS-System.
1. On the destination DS-System's Customers Tab, browse and highlight the DS-System Name.
3. Click Import Customer. The Import Customer screen appears.
- F1 Help: See "Import Customer / DS-Client".
4. Type the source path from which to copy the customer data.
5. Click OK. This process will automatically create the Customer and DS-Client accounts, as well as copy the backup data to the DS-System.
- If DS-System can find a storage location on the same volume as the specified path, a popup screen appears:
- F1 Help: See "Select Import Method".
- The Move option is faster, but the data (not including Library files) will be moved to the one storage location. Therefore the storage distribution may not be balanced after Import.
- If the logical size (available to DS-System in the storage location) is less than the data being moved, a warning appears. There is enough physical space because the move process is just renaming files in the storage location. However, DS-System will not put new files into that storage location if DS-System has no available logical space.
- If DS-System cannot find a storage location on the same volume as the specified path, a popup screen appears. If you click Yes, DS-System will automatically balance the import of data among all its storage locations:
- The Select Storage Group screen appears if the DS-System is going to balance the data across storage locations. In this case, you must select a Storage Group. (See "Extensible Storage".)
- F1 Help: See "Select Storage Group".
6. You will be asked if you want to overwrite the Global Options for the current DS-System (Additional Charges, Billing Plans, Business Parameters).
7. Once complete, the DS-Client number and DS-System IP address will be changed.
8. On the old DS-System, for each migrated DS-Client on the DS-System Tree, right mouse click and select New Registration Info. The Enter New Registration Info screen appears.
- F1 Help: See "Enter New Registration Info".
9. Enter the new information. The customer will see this when trying to connect to the old DS-System.
10. You must tell your customer their new DS-Client number, and have them configure their DS-Client as follows:
- For Windows DS-Clients: Have the customer run Start > All Programs > Asigra DS-Client (or your Branded Service Name) > DS-Client Setup and change their DS-Client number and the DS-System IP address.
- For UNIX DS-Clients: Have the customer rerun the installation (setuplinuxclient.bin) and change their DS-Client number and the DS-System IP address.
11. To make it easier for your customers, you can create a DS-Client Registration Information (.CRI) file for EACH of the migrated DS-Clients. (See "Export DS-Client Registration Information".).
