Thanks! I must admit that I don't really understand what you mean by "You have to use touch on your server to change it.", but I'll try to explain a bit more:
When I upload files with WS_FTP (my ftp program) there is a configuration setting where you can select if you want to keep the original timestamps or not. However, there is a note in the setting description that 'MDTM support is required to preserve time.'
This works on some servers, but some always generate a new stamp. The latter is the case with the Plesk VPS server I'm currently trying to set up.
Regardless if the file is new, or if I'm overwriting a file thats already exist at the server, the timestamp is always set to the time of upload.
It's important for me to keep the timestamps if I have the restore the server from my local backup. F.ex. I have some gallery folders containing photos and I must be able to list them chronologically at the server based on their original timestamp.
Also, keeping the timestamps is handy when it comes the verify file revisions.
So my question is how to enable MDTM support for my VPS.
