This is the result: ls -a /zroot/.zfs/snapshot/*14d /zroot/.zfs/snapshot/2017-10-10_11.10.00--14d: . .. /zroot/.zfs/snapshot/2017-10-10_12.10.00--14d: . .. . . . /zroot/.zfs/snapshot/2017-10-23_14.10.00--14d: . .. This is busy system and I have made many changes to the file system since starting this on October 10. Why are there no snapshot references to changed files or where do I find them? -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
