Hi,

In your case, there does not need changing Volume Retention value in
Pool Resource if it is set properly. Rather you should look into Job
Retention and File Retention periods both for Client resource and Pool
resource. The simplest way to do this is turning off AutoPrune to
Client resource and if you have this directives in Pool resource too
then you can remove them from Director configuration file. Eg.

Client {
    Name = "aaa"
    AutoPrune = no
}

If you really need to use above described directives then you should
set proper value for each one.

With AutoPrune there is one subtle trap. If you does not have
AutoPrune directive in Client resource then it still works due to
AutoPrune is default turned on. So be careful :)

You can create bootstrap file for extract the only needed files from
volumes by bextract. Another way is using an include list to bextract
tool. Good practice is using smaller file volumes sizes (eg. due to
your described problem).
