Does Windows file share (samba protocol) have an incremental API?

I'd like to query a windows share for "all files added/edited/removed since timestamp yyyy/mm/dd hh:mm:ss"



Does such a thing exist?



The only thing I know of is inotify - is this the only option?



https://stackoverflow.com/questions/8124617/getting-file-create-notifications-for-cifs-mount-in-linux



inotify is not really what I want because that is push based when I'm looking for something I call poll.



Kind of sounds like what I'm looking for doesn't exist, but I figured I'd ask here to see if anyone has heard of anything.

          Apparently no.



          Windows itself (through local disk access) would offer the USN journal, which has the ability to query all changes since a specific journal entry index (you would then store the 'current' index along with every backup). However, this is not available via SMB, according to MS-SMB appendix A section 136:




          Windows does not support USN journal calls because they require a volume handle. The following USN journal calls are also failed with STATUS_NOT_SUPPORTED.



          FSCTL_READ_USN_JOURNAL, FSCTL_CREATE_USN_JOURNAL, FSCTL_QUERY_USN_JOURNAL, FSCTL_DELETE_USN_JOURNAL, FSCTL_ENUM_USN_DATA




          You can also dig through the other SMB messages documented in MS-SMB or MS-SMB2 (section 2). I could not find any messages which would search for files in any way except for enumerating a single directory. (In any case this would be somewhat unusual for a filesystem protocol to have...)
