Not backing up all files in Deduplicated directory

Hi.
Im running version 8.4.3. Installed on an X64 windows 8.1 machine.

When I try to back up my file server, or any directories on it (using any option on file protection) it only ever backs up about 10-20% of the data.
The file size of the back up is generally about 10% of the original size, and when I browse through the back ups in the restore console a huge number of files are genuinely missing and therefore unrestorable.
I get shed loads of skipping reparse points messages as well. Im not sure what these mean, but I assume they refer to files that have been deduplicated and therefore some or all of the file is located elsewhere.
I have submitted this via the help console with whatever diagnostics get sent through as well, but had no response.

The server holding the files I am looking to back up is a 2012 Hyper-V server. The directories are deduplicated. I have tried backing up to a NAS and to a local directory on the machine holding BackupAssist. Results are identical.
When I copy a directory to the C drive of the BackupAssist machine, and back that up to the NAS, it is all fine. The exact same directory copied from the deduplicated file server backs up about 12% of the files therein.
All other settings for the back up remain identical.

How do I make this work? I don't want to do a system protection back up, I just want to back up all the files within these directories. I am happy if it loses the dedupe in the process of the back up, and the back up therefore becomes larger than the original.
However, you report the software as being compatible with the O/S's and dedupe, so I assume Im missing a trick.

Hi

It's Tim from BackupAssist.

We recommend using System protection for backing up de-duplicated volumes:

The following article explains how BackupAssist handles deduplication:

I hope this helps.

I did look at that post, and was happy that the de-duplication would be lost using file archiving and file protection options. However the post doesn't indicate that they are unable to back up deduplicated files at all.

Im not keen on using the system protection option for two reasons. It only appears to work for a local machine to the installation and BA is installed on a different machine and, more importantly, to do the entire system rather than the two directories I need would over treble the size of the back up

Hi Martin,

Unfortunately the System protection backup option will be the only way to proceed and you will need to backup full volumes and not only selected items.

As you have mentioned, System protection will need a copy of BackupAssist to be installed on the server.

Tim

Does that mean then, as the software can not do what you say it will on your web page and in your sales, you will be able to provide me with another licence to allow me to install it on the second machine?
