Running V 2.4.6 on my 2Tb drive. It all works fine, backing up on the fly as I have it set to continuous backup.
Some weeks ago I installed an update and had some problems with continuous backup and set it to timed (hourly) backup for a while. Eventually got it back to continuous backup and it is working fine. The problem is that quite frequently, about hourly (though it may be related to my usuage) I get this data transfer which Networx shows as being between 200 & 300 Mb/s, lasting for a minute or two, which not surprisingly practically brings my PC to a standstill. Drive is networked by cable via an unmanaged switch through gigabit ports.
It didn’t used to do this big transfer, so why does it now? It is as though it is copying the entire backup area in order to filter out the changed files rather than just backing up the changed files. If I have Smartware open and look at it, it will change status to “copying files” for a short while without showing massive data transfer.
