ReadyNas 2304 Backup to ReadyNas2304 - Disk Consumption Differences
I have had a RR2304 in service for over two years, configured with 4x8TB WD Red drives with a single volume configured in RAID6, and two shares. Both shares are configured to snapshot daily. This i...
Do you have any links to files across shares? If so, your copy is likely actually copying the file to both places, not the file and link.
If the production NAS were old enough, I'd say it was due to a different sector size, but I don't think that's been updated in the past two years.
However, I have seen similar discrepancies, though not as severe as yours. I totally re-configured a NAS and restored from backup, and the resulting used space was larger. Like you, I calculated the actual use and found the newly reported volume use to be more accurate. I did not pursue the issue any farther, but I can see how an incorrectly reported use on you production NAS (assumning that's the case) could lead to running out of space before you expected to.
That I shared your experience doesn't really help you, but I hope it lets the Netgear mods know it's probably not unique to you.
That is helpful to hear, and I agree. It needs to get out there. There are no links to data across shares on the production NAS. There is repeated data, as I had originally scheduled a backup (using a different machine to calculate the sync) from one share to the other for "anti-user" redundancy in the event that individual files needed to be recovered. But to be clear, it is not linked, and it is a very small portion of the data. It sure looks like the first NAS is calculating usage incorrectly, at a very alarming disparity.
