Hi Jim,  no - we still keep all of the checkpoints around (unlike some other NAS vendors).  In fact the first thing that happens when you execute a restore is than an extra checkpoint get created so that you can undo the restore  Rainer  [nasadmin[NAME] ~]$ fs_ckpt rainer -lid    ckpt_name                creation_time           inuse fullmark   total_sa                             vvol_used  ckpt_usage_on_savvol73    Monday                   04/19/2010-17:45:58-CEST  y   90%        16%                                             3%74    Tuesday                  04/19/2010-17:46:42-CEST  y   90%        16%                                             3%75    Wednesday                04/19/2010-17:46:45-CEST  y   90%        16%                                             3%76    Thursday                 04/19/2010-17:46:47-CEST  y   90%        16%                                             3%77    Friday                   04/19/2010-17:46:49-CEST  y   90%        16%                                             3%  [nasadmin[NAME] ~]$ /nas/sbin/rootfs_ckpt Wednesday -Restoreoperation in progress (not interruptible)...id        = 75name      = Wednesdayacl       = 0in_use    = Truetype      = ckptworm      = offvolume    = vp175pool      = clar_r5_economymember_of =rw_servers=ro_servers= server_2rw_vdms   =ro_vdms   =checkpt_of= rainer Mon Apr 19 17:46:45 CEST 2010deduplication   = Offused      = 19%full(mark)= 75%stor_devs = CK200073500350-0009disks     = d9disk=d9    stor_dev=CK200073500350-0009 addr=c0t1l0         server=server_2disk=d9    stor_dev=CK200073500350-0009 addr=c16t1l0        server=server_2 [nasadmin[NAME] ~]$ fs_ckpt rainer -lid    ckpt_name                creation_time           inuse fullmark   total_savvol_used  ckpt_usage_on_savvol73    Monday                   04/19/2010-17:45:58-CEST  y   75%        19%                3%74    Tuesday                  04/19/2010-17:46:42-CEST  y   75%        19%                3%75    Wednesday                04/19/2010-17:46:45-CEST  y   75%        19%                3%76    Thursday                 04/19/2010-17:46:47-CEST  y   75%        19%                3%77    Friday                   04/19/2010-17:46:49-CEST  y   75%        19%                3%78    rainer_ckpt1             04/19/2010-17:48:57-CEST  y   75%        19%                3%
We have a nfs filesystem that we take periodic checkpoints on (both manual and scheduled). For example, we have a checkpoint dated 4/01 and one dated 4/10. What happens to the 4/10 checkpoint if we perform a Full Checkpoint Restore to the original filesystem using the 4/01 checkpoint?  Does this make the 4/10 checkpoint irrelevant after this Checkpoint Restore?  Thanks.  Jim
