Nicodem Posted September 15, 2023 Share Posted September 15, 2023 Hi I need to move total of 24TB of data from one running Unraid to new one. Both are with 1 Gig connection, same network. I found out that quickest way for me to do this is to go with standard FTP server as everything is local, no secure issues. However I see very strange drops in copying files. Goes up to limits of LAN then drops dramatically basically to zero and again and again. Total speed then is not even close to half of possible one. Here is how network traffic looks like: any idea what could be a problem here? What is a bootleneck? System I pull data from - NUC i7 10th gen with 32GB RAM and unfortunatelly 2 disks connected via USB 3.0 there (thats why I am moving data) System I copy to is based on Asrock N100M motherboard (N100 intel) with 1 parity drive on MB Sata controler and 4 SATA on PCIE controller.

Solution JorgeB Posted September 15, 2023 Solution Share Posted September 15, 2023 Is turbo write enabled on the destination server? You can also mount the share(s) from one of the servers with UD and use rsync instead. Quote Link to comment
Nicodem Posted September 15, 2023 Author Share Posted September 15, 2023 OMG, I think this turbo-mode did a trick here. Thanks! I will come back to normal setting once finish (in few days...) I would prefer to go rsync but also found out that this was choppy. What did you mean by "UD" - mapping via SMB and then manual rsync? I thought that FTP should be quicker. Quote Link to comment
JorgeB Posted September 15, 2023 Share Posted September 15, 2023 rsync via smb won't be faster, it's just usually simpler to use and very easy to resume if needed, but if you are good with ftp it's a fine alternetive. Quote Link to comment
Nicodem Posted September 15, 2023 Author Share Posted September 15, 2023 These are multimedia files for Plex so FTP copy is fine for me but yes - will switch to rsync once I will come to part of copying backup files just to be sure. thanks! 1 Quote Link to comment
