Thank you for sharing your detailed setup and migration plan. Moving from a RAID5 with 4x4TB drives to a RAID6 with 4x12TB drives requires careful planning to ensure data safety and minimal downtime. Here’s a step-by-step backup and restore strategy to ease your concerns:
Backup Strategy
Hyper Backup Validation:
Before proceeding, validate the integrity of your Hyper Backup by running a backup integrity check in Hyper Backup. This ensures your backup is complete and restorable.
External Backup:
If possible, use an additional external 12TB drive to create a secondary backup using Hyper Backup or Synology Drive. This adds redundancy in case of unexpected issues during restore.
Snapshot Replication:
If you have Snapshot Replication enabled, take a snapshot of critical files for quicker recovery during testing.
Migration Plan
Backup All Data:
Ensure all data is backed up and verified before proceeding.
Install New Drives:
Remove the existing drives and insert the new 12TB drives. Start with 3 drives in RAID5 to allow for functionality testing.
Restore Data:
Use Hyper Backup to restore data onto the new RAID5 array. Test the functionality of your applications and ensure all data is accessible.
Transition to RAID6:
Once testing is complete, add the 4th 12TB drive to the RAID5 pool and convert to RAID6. Synology DSM supports RAID migration without data loss.
Monitor the process carefully, as RAID migration can be resource-intensive.
Tips for Smooth Restore
Ensure Consistent Backups: Before starting, run a final incremental backup to ensure all recent changes are included.
Test Backup Restore: If possible, test restoring a small portion of your backup onto a temporary external drive to verify data integrity.
Allocate Time: Full data restoration and RAID migration can take several hours or days depending on the size of your data and system performance.
