SW 126.96.36.199 backed up the PST files at the point when Outlook was closed, usually within about 10 seconds. I was turning SmartWare on and off manually, because of the WDFME problem, and usually only backed up once a day so any 24 hour rule would not have been obvious.
With SW 1.6 the behaviour seems to have changed and several people have reported that their PST files are not being saved.
My own experience is that the files seem to be backed up although SmartWare says they aren’t. For example Outlook was closed yesterday evening soon after 23.00. By 23.15 my PST file was backed up in the swstor showing a ‘modified time’ of 15.22 on 15 May, which I think was when I had opened Outlook.
However SmartWare says ‘Partial Backup Accomplished’ and that the PST is a file which ‘Failed to Backup’. Under ‘View Files’ it says the reason is ‘File pending backup’ with a time of ‘5/15/2012 11:10:19 pm [ie 23:10]’. So the file waiting to be backed up, and which failed to back up (according to SmartWare), appears to be a file which has been backed up (according to Explorer).
The ’24 hour’ rule may explain why PST files were backed up when I left SW running for several hours with Outlook closed.
This pattern of behaviour has been consistent since I installed SW 1.6.
I have re-opened and closed Outlook several times since then and the PST file has not been backed up which seems to confirm the ‘once every 24 hours’ rule. SW still says ‘File pending backup’ with a time of ‘5/15/2012 11:10:19 pm’.
So; I suspect that the 24 hour rule applied with SW 188.8.131.52 but I don’t know; SW 1.6 is probably backing up the PST files but telling me (and other users) that it is not. I haven’t tested a Retrieve.
I have reported this to WD.
