    Default gfs rotation with 3h,day,week,month ... ?

    hello

    is it possible to use amanda so i can implement a grandfather-father-son rotation scheme that would allow for retention of the following

    3h,6h,9h,12h,24h,36h,48h,3d,4d,5d,6d,1w,2,w,3w,1m, 2m,3m,4m,5m,6m,1y,2y,3y

    first question is can amanda manage the tape rotation ?

    and what kind of cron schedule could in implement for that ?

    i have tried to do one but i ran into the 28/31 days month and the 6m/= 26 week issue

    using debian with latest amanda release

    the amount of data to backup is quite small, but i need to backup often (user missclik protection) and have a variable retention time (days for the "oops i think i deleted that 3 day ago" and years for the law)

    i have done a plan of the vtapes to be used, wich i attached here (open office sheet) and a crontab

    0 3,6,9,15,18,21 * * * /3h script
    0 12 * * * /12h script
    0 0 2-7,9-14,16-21,23-28,30,31 * * /24h script
    0 0 8,15,22,29 * * /weekly script
    0 0 1 2-5,7-11 * /monthly script
    0 0 1 6,12 * /semstrial
    0 0 1 1 * /yearly

    also what kind of .conf, 1 per set i assum, parameters should i pick ? like tapecyle etc

    ofc i have googled and tried to find rotation calculator but havent found any free

    any help welcome

    thanks
