Known Affected Releases

10.0(1) 8.6(2) 9.1(2)

Description (partial)

Symptom:
CUCM 8.6.2 or 9.1(2) and later DRS backup may fail due to interoperability issues with Windows 7 or Windows 2008 based SFTP servers or any SFTP server which uses SMB2 to access disk storage.

Conditions:
This has been observed under Windows 7 and Windows 2008.

To check if you are affected please conduct the following steps during file upload to your Windows-based SFTP server:
a) open CMD and change your current folder to SFTP root directory
b) issue dir command to check what is the size of the file being uploaded
c) you are affected if the file size is 0, it is not increasing, and it gets updated as soon as you issue dir /R command
