Local to Remote Server Migration
Overview
Local to Remote Server Migration is a useful feature to quickly move large backup data from the client machine to the backup server. Using this feature, the initial seed backup can be taken in a local external drive connected to the client machine and the external drive can then be physically moved to the remote backup server’s environment to migrate the data into the backup server. After the data migration and after performing the server side and client side Local to Remote server migration steps, the incremental backups can run directly from the client to the remote backup Server.
Local to Remote Server Migration
-
Configure a backup schedule in the StoreGrid client system. Log into client’s StoreGrid web console page and select ‘Backup -> Add Backup Schedule' from the top menu. ‘Add Backup Schedule’ link will take you to ‘Create a new Backup Schedule’ page.
-
Select the ‘Backup Type’ as ‘Same Machine’ in Step 3 and enter the external drive location for the ‘Local Backup Location’. After entering all the other backup details, save the backup schedule.
Note : ‘Same Machine' backup feature is available only from 2.3 release. It can be used only for 'Local to Remote Server Migration'; you cannot restore from the ‘Same Machine’ backup.
-
Run the backup, check the progress and make sure the backup runs to completion.
-
When the backup is complete, suspend the backup schedule.
-
Disconnect the external drive from the client machine and connect the external device to the remote backup server.
-
Copy the client's data (Z:\backup\1) from the external device to some temporary location in the drive where you are planning to store the backup data in the remote backup server. Like for example, if you storage device is the E: drive, then copy the data to say “E:\LTOR”. You don’t have to copy the data to the temporary location and you can migrate the data directly from the external drive itself. However, the migration might take a little longer to complete, based on the speed of the external drive.
 
-
Go to the remote backup server’s web console "Server Admin-> Group Management -> Local to Remote Server Migration (Icon)" page. Enter the location of the client's data followed by the 1/ directory. For example, if you have copied the client's data from the external drive to the temporary E:\LTOR location in the backup server, enter location as E:/LTOR/1/ in this page. If you have not copied the data to a temporary location, enter the location of the external drive, like for example Z:/backup/1. After entering the path, click on the "Submit Location" button.
-
The client name will be displayed. Select the client. If you are doing the data migration from this client for the first time, enter the target group under which the client is to be migrated and the location where the backup data is to be stored. Click the "Migrate" button.
-
In the client system, take a backup of the <StoreGrid Installation Location>/data/<backup name>/sgprp.db file. This is just to ensure you can recover this DB file if you need to do the client side migration again, if required.
-
Go to “Administration -> Advanced Options -> Local to Remote Server Migration” (Icon) page in the client machine. Enter the remote backup server name for the new backup server name. Choose the option “No, backup only to new server”. In table listing the backup schedules, select the backup schedule(s) whose data has been moved to the new backup server. You can select all the backup schedules by checking the checkbox against the "Available Backups" column name. Confirm that the backup data of the selected schedules has already been moved to the new server and that you have run the server side local-to-remote-server migration module in the remote backup server (confirm from the check box).Click the Migrate button to complete the migration.
-
To confirm that the migration has been successful, try running an incremental backup. If the incremental backup runs fine, the migration is successful and you can delete the backup of the db file that you created in step 9 above. If the client starts taking a full backup, then suspend the backup, replace the sgprp.db file with its backup that you created in step 9 and check the server migration steps again.
Troubleshooting Tips
Limitations
- When StoreGrid is stopped during Server side "Local To Remote Migration", it cannot be resumed later from where it has been left. It has to be run afresh again.
- Server side "Local To Remote Migration" report cannot be seen once you leave the web console page.
- When there isn’t enough Space in the remote backup server, migration will still proceed to completion by automatically taking the necessary space.
- File version migration is not supported. Only full backups and incremental backups can be migrated.
