DCE backups do not overwrite one another. A share may eventually get too full to accommodate more backups.
You cannot delete backups that exist on a share from the DCE client. You must access the shared drive/folder directly to delete old backups or add space to the current allocation if more space is required.
Data Center Expert versions before 7.3.1 do not support mounting to shares that require NTLMv2 authentication. In some situations, the test mount might be successful, but does not authenticate. For DCE 7.3.1 and earlier, you must use a share that allows NTLMv1 authentication.

SMBv2 and higher support
Data Center Expert does not currently support versions of Server Message Block (SMB) higher than version 1. We are working on upgrading the operating system Data Center Expert uses to allow support for newer SMB versions.
Microsoft began disabling SMBv1 in Windows Updates. This can cause Data Center Expert to be unable to back up to existing shares or mount new shares. More information about enabling SMBv1
