This is a modified version of the snapman.pl script sample from NMSDK 5.4.
It has been tested on cDOT 8.3.1P1 on data and archivelog volumes of a database when set in backup mode.
You can list the existing snapshots, create a snapshot for each volume in the list with a prefix, delete any snapshot created before a specific elapsed time.
You need NaServer.pm and NaElement.pm present in the same directory as this script.
You may also need the following packages (in Ubuntu) liblwp-useragent-determined-perl libxml-parser-perl perl-doc
