Re: Why is is dedup cache file not excluded by default ?

[Erwann SIMON]

Hi all,

I think we all agree that backing up this dedup cache fiche is useless and that 
it can considered as as a best pratice to exclude it since trying to back it up 
generate retries.

Stephan is right when it writes that almost nothing is excluded, except this 
.TsmCacheDir directory (and system state files excluded by VSS on Windows 
clients). It seems that it's not an habit.

Since the file has a name built frm know informations : DEDUPCACHEPATH option, 
Server Name and Node Name, I think it could be hardocded without any risk to 
exlclude any another file.

Ha, I didn't know that! I guess there is one directory excluded by default.
Thanks for pointing that out.

Re: Why is is dedup cache file not excluded by default ?

Hello,

your presumtion doesn't seems accurate to me (Windows, Linux, AIX clients,
mostly v7.1):

tsm> q inclexc
*** FILE INCLUDE/EXCLUDE ***
Mode Function  Pattern (match from top down)  Source File
 - -- -
No exclude filespace statements defined.
Excl Directory /.../.TsmCacheDir  TSM
Include Snapshot Retry
TSM500*/opt/tivoli/tsm/client/ba/bin/dsm.sys
No DFS include/exclude statements defined.

Any directory .TsmCacheDir is excluded by software itself

Re: Why is is dedup cache file not excluded by default ?

[Stefan Folkerts]

For as far as I know nothing is excluded by the code itself and I think
this is a policy thing.

Since you can install the software in different locations and you can use
different names for different files (ie log files) IBM can never be 100%
sure that the file it is hardcoded to exclude is the file we think it is.
There is always that chance. It would have to be hardcoded as a sort of
dynamic exclude like "I will exclude this is cache file that I am currently
actually using during the each backup".

Hi Rick,

Yes, this is what I always do. But I was wondering why it's not excluded by the 
code itself.

Erwann,
I have client option sets defined on the server that I use to globally exclude 
it from all file level backups.

Hi all,

I'm wondering why the dedup cache file (TSMDEDUPDB_servernamenodename.DB, 
located in the dedupcachepath directory) is not excluded by default ?
I generally exclude it because it causes somes retries and do think that 
there's no need to back it up. But I may be wrong.
So, must we really back it up ? And why ?
