Thanks Gavin. I'm not sure what you mean by "share path". As far as copying to same location, on both computers its c:/MediData/RMData, if that's what you mean. I copied the entire Medidata folder on older computer making a winzip file, then copied it to new computer and the RM Data worked, it replicated. So there must be something in my backup. I'm backing up the entire folder (with the exception of an old InterfaceEDI folder that's in there that I no longer use) and then pulling that entire folder from the backup and restoring on new computer and the RM Data isn't the same, its showing ERA's that have been posted and archived. I've looked at the files contained in the folders for dates, etc to be sure they are all there and the same, and they are. My backup is doing incremental backups, so I'm wondering if that is messing something up, but I can't imagine why. The RM Data on the new computer isn't showing ALL ERA's I've received, posted and archived since March, just some of them but since I have over 90 practices that "some" is actually alot. I'm going to play with it some more later today, I'm actually doing another restore right now on the new computer with last nights backup to see what happens but i expect the same results since I've done it numerous times already. You mentioned Windows backup, I've never used that but I'll take a look at that, if I can use Windows backup, then back that up to my online backup, I'll see what happens. Any other ideas though? What file under RMData contains info about what's been posted/archived and what hasn't? I imagine each practice under Mediata/RM Data has a file that has that info, and I've crossed checked a few and the files/dates are the same on each computer so I'm at a loss. If you can point me to that file, I'll try doing a direct copy/paste to the new computer, and if it works then that answers some questions.
