Media Pools To share tapes among different jobs with different backup methods, BrightStor ARCserve Backup uses the same GFS rotation naming syntax, but it uses a different naming convention for backup types when the Append Media feature is enabled: (backup type)-(user-defined media pool prefix)-(day-of-the-week)-(date) Without Append Media F - full backup I - incremental backup D - differential backup W - weekly backup M - monthly backup With Append Media A - full backup A - incremental backup A - differential backup W - weekly backup M - monthly backup If you submit GFS rotation jobs with the Append Media feature enabled, you can maximize media usage by submitting multiple jobs using the same media pool and use the previous day's tape within the current week. For example, if you submit three GFS rotation jobs all using the same media pool and 5-day rotation scheme, all three jobs share the same set of tapes. In addition, multiple days can share the same tape, drastically reducing the amount of tapes you use: ■ Monday, Tuesday, Wednesday, Thursday = One tape that includes full backup data from job 1(day 1), job 2(day 1), and job 3(day 1), and incremental backup data from job 1 (days 2, 3, and 4), job 2(days 2,3, and 4), and job 3(days 2,3, and 4). ■ Friday = One tape that includes weekly backup data from job 1(day 5), job 2(day 5), and job 3(day 5) This results in two tapes for the week. 7-18 Administrator Guide
