I have been watching an initial TSM backup running for a long time now over a WAN connection (100mbit/sec) and I keep seeing "compressed data grew" followed by a "Retry". Does this mean that for ever

Good morning Tom, We have, successfully, used the following in our dsm.opt/dsm.sys files for many years EXCLUDE.COMPRESSION "*.z" EXCLUDE.COMPRESSION "*.*_" EXCLUDE.COMPRESSION "*.pst" EXCLUDE.COMPRE
You can specify 'compressalways yes', which will prevent the retry. However, you then have to live with the fact that the file is expanded in TSM storage. I believe this problem does not apply to LZ4

The client is 7.1 but our servers are still at 6.3. Also I had to switch to a storage server that does not have dedup on it as that slows the WAN transfer way down (I only get about 20% network utili

Ditto, I use a similar approach. I have them in a client option set on the backup server so they can be easily managed in one location. -Rick Adamson Good morning Tom, We have, successfully, used the

Hello Pamela, You should propably add the Open XML Microsoft Office file extensions to you list (docx, xlsx, pptx...) as they are XML compressed files. -- Best regards / Cordialement / Erwann SIMON -

They are actually ZIP files. If you rename a .DOCX file to .ZIP you can open it with WINZIP and see all of the files within. On Thu, Jun 30, 2016 at 10:10 AM, Erwann SIMON <erwann.simon AT free DOT f
The legacy LZW compression can grow files that are already in a compressed format. The newer LZ4 compression should not grow an already compressed file. In that respect, it's similar to the compressi

If the server is at 6.3.x and the client is at 7.1.x can it use LZ4 or does that require the server to also be at 7.1.x? On Thu, Jun 30, 2016 at 12:06 PM, Paul Zarnowski <psz1 AT cornell DOT edu> wro

Tom, In order to be able to use client side LZ4 compression, the server must be at least at 7.1.5 and the client at 7.1.6. Moreover, client-side compression and client-side deduplication must be used
