------------0E91DF09008489B3C Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Hello FreeBSD, I have a ZFS filesystem, which have daily snapshots. User removed several multi-gigabyte files by accident and need to get them back. These files are present in old daily snapshots, allright. But as far as I understnad, if I do cp /fs/.zfs/snapshots/old-snapshot/file /fs/file I got TWO copies of this file (one in live filesystem and future snapsho= ts and other one in old snapshots). As files in question are multi-gigabyte (about 100G alltogether) I don't want such duplication (dedup is turned off, as it is very memory-consuming). Is it possible to restore these files without such data duplication? I could not rollback whole FS to old snapshot, as here was other changes to it after files removal. --=20 Best regards, Lev mailto:lev@FreeBSD.org ------------0E91DF09008489B3C Content-Type: application/pgp-signature -----BEGIN PGP MESSAGE----- Version: GnuPG v2.0.22 (MingW32) iQJ8BAEBCgBmBQJWkZnkXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRGOTZEMUNBMEI1RjQzMThCNjc0QjMzMEFF QUIwM0M1OEJGREM0NzhGAAoJEOqwPFi/3EePmrkP/1YUqUkqFX5twZ0x0Oej5ekr X/n31zHx31VNbJrMQjFZKMEJh/wDsGq8TTVKgdb1IlhuX+SgwNFpGgdnbLELyBZJ HWyOtBsNjZvRePCAZsQUEPO+uMLEUIkMYoZY/KlwaW8QGhTMr8lPl8oTA0cR0DiN Rp0lfyCKlK9rYMgqivDrVh8iX1Cn2VHLGXPU8B8erYTIFJ9ogTnZJkcBuT0qp468 rMNN28e5qXRmajS7gepKoq3O2n5uoAGYWOgumsyowM3FebBtue8hX1yLvItCEn8d q38ISw+iUQ6i54lgFU1sOmiMg03r9/5sq01R+s9Rjqdze7YNHHOuM22B9fSh0Ll7 aPwNe7wMZEUgWiUa7Oa61G6gmlpUhmAB8lTK2+kt/h/Ets1oP/f+DnC7SDXoE5yj xcSUFkyUf6FRbRBDI8TDBYZ49gU7iHJXJMGSab524bVSUz3itCOkYysGwCrfGaXu Ouk/OZyuB8GuHIr8cvkc6EbfNX5Et14Myq5bQMIClzRn3rNBxOXT7EKpkQwMyC8o bWU+RX1pTRTQkiyubkFQ80UPZM91+nJe+LfZIJaKtS4nEOKnmHI8H6VwBFntxg2M Ehz9cjc3XZKOuPdkXew20AClLbH0ZKkwZOVtqiLROaTzlEwAbhA9A0Jv7G3mgXM8 uEoJTrJEsR6d46xx0ztO =+3Un -----END PGP MESSAGE----- ------------0E91DF09008489B3C--
