Most command line tools aren't aware of directory hardlinks which are used by Time Machine to create the illusion that each snapshot contains a complete set of files. If you use the command line to try to delete a single file or directory from a particular snapshot it's likely you will actually end up removing that version of the file or directory from every snapshot where it existed. If you try to delete an entire snapshot from the command line you may also remove identical files/directories from every other snapshot. Either outcome is bad for the integrity of your Time Machine backup. - Chris > Thanks > > Jerry > >> >> On Dec 6, 2011, at 8:02 AM, Jerry Levan <[email protected]> wrote: >> >>> Hi, >>> >>> I used an attached disk for several weeks for a time machine backup >>> destination. >>> >>> After I added a NAS I no longer had any use for the older Time Machine >>> backup. >>> >>> The backup is heavily protected by ACLs and I don't seem to be able to find >>> a magic command line that will recursively strip the ACL protections so I >>> can delete the 'whole thing'. >>> >>> Google seemed to think that there is a function 'fsaclctl' that can remove >>> ACLs from a device but it does not appear to exist in mac osx 10.7.2 client. >>> >>> Nuking the entire partition via disk utility seems a bit heavy handed… >>> >>> Any suggestions? >>> >>> Jerry >>> >>> >>> _______________________________________________ >>> MacOSX-admin mailing list >>> [email protected] >>> http://www.omnigroup.com/mailman/listinfo/macosx-admin > _______________________________________________ MacOSX-admin mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-admin
