you may use ZFS snapsots and the zfs diff command S0013(root)#~> zfs list | grep V0002_PA_arch/data/apsys_dbprod V0002_PA_arch/data/apsys_dbprod 2.73M 358M 2.71M legacy V0002_PA_arch/data/apsys_dbprod@2012-09-24_Back 22K - 2.71M - V0002_PA_arch/data/apsys_dbprod_arch 1.95M 358M 1.93M legacy V0002_PA_arch/data/apsys_dbprod_arch@2012-09-24_Back 20K - 1.93M - S0013(root)#~> zfs diff V0002_PA_arch/data/apsys_dbprod@2012-09-24_Back V0002_PA_arch/data/apsys_dbprod S0013(root)#~> touch /zones/V0002/root/apsys/dbprod/newfile S0013(root)#~> touch /zones/V0002/root/apsys/dbprod/newfile-2 S0013(root)#~> zfs diff V0002_PA_arch/data/apsys_dbprod@2012-09-24_Back V0002_PA_arch/data/apsys_dbprod M /zones/V0002/root/apsys/dbprod/ + /zones/V0002/root/apsys/dbprod/newfile + /zones/V0002/root/apsys/dbprod/newfile-2 Regards Christian _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
