The only file that gets kept for retonly days is the copy of the file that
was deleted from the filespace.  All the other copies are kept for 30 days
with the active file (a copy of the file on the filespace that has not been
deleted) being kept forever (as long as the file on the filespace isn't
deleted).

If your goal is to be able to offer the user the ability to restore a file
to any state within the previous 90 days, say, then you should set things up
as follows:

Versions Data Exists       unlimited
Versions Data Deleted      unlimited
Retain Extra Versions       90
Retain Only Version          90

You set the versions to unlimited since there is a possibility you could
perform backups more than once per day.  Is this setting going to consume
lots of space on your server?  Consider that the vast majority of files do
not change everyday.  Only some of them.  Keeping a big database this long
could be a problem so don't do that!  You would probably never restore a
database back 90 days anyway.  But then someone will scream "but what about
long term archive of databases?"  Export to ascii and use Arvhive, not
backup.  See my paper!

Am I rambling?

hello to all,

consider this: retain extra is set to 90 days, retain only is set to 30
days. I4m doing an daily incremental backup, after this I delete the file
xxx from workstations disk. How long the tsm server is keeping the file xxx
? 30 or 90 days ?

I defined the copy group like this:
 Versions Data Exists       3
Versions Data Deleted    3
Retain Extra Versions       90
Retain Only Version          30
Copy Mode                          MODIFIED
Copy Serialization             SHRDYNAMIC
Copy Frequency                0


The documentatios says:

RETExtra
     Specifies the number of days to retain a backup version after that
version becomes inactive. A version of a file
     becomes inactive when the client stores a more recent backup version,
or when the client deletes the file from the
     workstation and then runs a full incremental backup.

RETOnly
     Specifies the number of days to retain the last backup version of a
file that has been deleted from the client file
     system.


Thank you !
