I've noticed that different departments have been purchasing their own NAS devices, mainly Buffalo, instead of using our centralized storage solutions. Now, we've been tasked with migrating all this data to network shares on our domain server. The challenge is to translate local accounts from the NAS to their corresponding domain accounts while also ensuring ownership is transferred correctly. The NAS disks are usually formatted in XFS or ext4, which makes using conventional Windows tools like Robocopy impractical since they're designed for NTFS. I've tried accessing the NAS via SSH, but it's not working for me. My thought was to use scp or rsync to transfer the data more efficiently while retaining ownership details. I'm also looking for any tools or GitHub projects that could help with this process. Has anyone dealt with something similar? Any suggestions on how to handle the data transfer or ownership mapping?

In my experience, Buffalo NAS devices are pretty straightforward, but they can be slow for transfers. Depending on your data type, you might want to try using compression algorithms first and then do a transfer via SMB. You'll still need to address permissions afterward though. I used a tool called 'Copyright 2' in the past to migrate databases and set NTFS permissions across different domains. It was about $40 for a license, but not sure if it'll work for local accounts—might be worth checking out though.
I’d suggest starting with rsync for copying the data. After that, you can set the permissions using something like aclmanager. Just keep in mind that ACLs can get messy when you're dealing with different devices, so it might take some tweaking.
Totally! Start with rsync and then adjust the ACLs as needed. Cross-device ACLs are definitely a headache!
For sure, rsync first, then fix permissions. ACLs can be a nightmare!
Great point! I like the idea of compressing data + using SMB. Thanks for the suggestion!
