Hi,
I have a DS918+ with 4 x 6TB drives that are all about 6 years old, in a SHR array with 1-drive tolerance. I have ~16TB of space of which 12TB is used. I recently bought 4 x16TB drives to replace them. My plan is to replace one drive at a time and allow the system to rebuild the array each time until all 4 have been replaced and the new array is completely re-sized to take advantage of the extra space. My biggest concern is that at some point during the 4 rebuilds, one of the old drives may fail and I'll lose everything. I do have everything backed up to local USB drives through HyperBackup, but I really dont want to have to re-create everything and do a restore that could take days. What I was thinking is; one of the folders contains several very large database files that I have completely backed up to a USB drive. If I delete those files from the storage prior to replacing the drives, there will be about 80% less data to rebuild, which should reduce the rebuild time and stress on the existing drives. I could then restore the files from backup and only the new drives would be affected. Does this make any sense technically? Am I missing something that renders this plan invalid? Also, what kind of restore time would I be looking at for ~10TB of data from a USB 3.0 drive through Hyper-backup?
Any responses are appreciated.
Thanks!
