Troubleshooting DCE backups

[EcoStruxureIT]

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.

SMBv2 and higher support

Server Message Block (SMB) v2 and v3 are supported in Data Center Expert 7.9.0 and newer.

Data Center Expert 7.8.1 and older do not support SMB versions higher than version 1.

Note: To backup DCE 7.8.1 to restore on DCE 7.9.0, you must use SMBv1. 

Microsoft began disabling SMBv1 in Windows Updates. This can cause DCE 7.8.1 and older to be unable to back up to existing shares or mount new shares.

More information about enabling SMBv1 

NTLMv2 support

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 older, you must use a share that allows NTLMv1 authentication.

Contact your local technical support to verify your software support and get update links.

FIPS mode

Data Center Expert versions 8.2.0 and newer support FIPS mode.

CIFS (Windows) mounts do not work when FIPS mode is enabled.

MD5 authentication is required for CIFS, which is not supported in FIPS mode.
