Microsoft error code listing:

" ERROR_SHORT_NAMES_NOT_ENABLED_ON_VOLUME

Short names are not enabled on this volume. 305 (0x131) "

 

A "destination" in Retrospect's parlance is always a media set, it is not an operating system. Please describe in more detail your setup.

The destination has multiple drive ...where backup stores....the partition is on basic and has capicty of 1 TB.

A "destination" is always a "media set". A "media set" has "members". Do you mean that your media set has more than one member?</p>

 

 

I quote rhwalker.

Please provide:

(1) complete version number of Retrospect

(2) complete version number of the OS

(3) complete description of hardware being used.

(4) complete description of the steps you are doing

(5) complete description of the problem

A "duplicate" is not a "backup". You should be performing "backups" instead. One major benefit is that you can keep many "backups" on the same "destination ( = "media set" ). With a duplicate, you can only save the last one on the same volume.

 

It isn't clear if you run the Retrospect Server on Windows 2008 or Windows 2012. No matter, as version 7.6 is too old to be supported on either of them.

I have a similar problem as <master> above. I am running the "Duplicate" function from a Windows Server 2008 file server to a Windows 2012 Storage Server. I am on Retrospect 8.2.0(177) running on a dedicated Windows Server 2008 R2 64-bit box with 32GB RAM.

 

I am doing the "Duplicate" function to clone my file server in preparation to transition to the 2012 Storage Server. I am also trying to duplicate the file permissions between the servers to avoid the tedious process of checking each folder for permissions.

So, I don't understand that the solution is to use "backup" instead of "duplicate".  I don't need backups because the file will never change.  I want to duplicate files that will never change.  Please advise what this error means:

 

MapError:  unknown Windows error 305

SetShortName:  USetFileShortName failed, G:\filename,  osErr 305,  error  -1001

System error code 305 is typically displayed as "ERROR_SHORT_NAMES_NOT_ENABLED_ON_VOLUME" and/or as the hexidecimal value 0x131. The message associated with this error code is "Short names are not enabled on this volume.".

Common Causes of System Error Code 305

Try run CHKDSK on the source volume.
