Rotation Example

This article details the setup of a standard GFS tape rotation scheme, while trying to keep each day's data on it's own tape if there is room.
Phase 1 is to create the media pools and set the lock date / EOL, Phase 2 is to setup media initialization tasks to do the actual rotation. By default Sesam will append all days at the tape daily00001 until it’s full. 

Requirements:

• SEP Sesam with a valid license
• 20 tapes (assuming an entire network wide full backup fits on one tape and is complete in <24 hours)

Phase 1: Create 3 New media pools:

1. Daily - Initialize 4 Tapes and set lock time / EOL to 4 days
   • Daily00001 for Monday
   • Daily00002 for Tuesday
   • Daily00003 for Wednesday
   • Daily00004 for Thursday
2. Weekly - Initialize also 4 Tapes and set lock time / EOL to 26 days
   • Weekly00001 for First Friday
   • Weekly00002 for Second Friday
   • Weekly00003 for Third Friday
   • Weekly00004 for Fourth Friday
3. Monthly - Initialize 12 Tapes and set lock time / EOL to 360 days.
   • Monthly00001 for January
   • Monthly00002 for February
   • Monthly00003 for March
   • Monthly00004 for April
   • Monthly00005 for May
   • Monthly00006 for June
   • Monthly00007 for July
   • Monthly00008 for August
   • Monthly00009 for September
   • Monthly00010 for October
   • Monthly00011 for November
   • Monthly00012 for December

Phase 2: Create 2 Media Events for media initialization (closing tapes)

1. Set up a scheduled mediainit for MON,TUE,WED,THU with the media pool “Daily” at e.g. 12 pm.
2. Set up a scheduled mediainit for FRIDAY with the media pool “Weekly” at e.g. 12 pm.
