Folks:<br><br><div>Thanks much for all of the responses yesterday with regard to my backup issue.</div><div><br></div><div>One of the advantages I thought I had with regard to the "cp" method was, if something turned up missing, I'd be able to nearly "click-and-drag" the backup file back to the system thereby restoring it. This was one of the reasons I'd not investigated "dump" or "tar" more closely yet.</div><div><br></div><div>I decided to try "rsync" because not only did some of you folks recommend and use it, but also I had a friend in MN who recommended it.</div><div><br></div><div>The partition I am trying to back up is coming from an NFS mounted volume and going to an attached external Firewire drive. The command I used in this test was:</div><div><br></div><div>/usr/bin/rsync -ral --progress --stats --times --perms /Volumes/mira/scsi /Volumes/burly_1/Mira/ --delete</div><div><br></div><div>Initially /Volumes/burly_1/Mira was empty.</div><div><br></div><div>All went fine for a few hours. Then, seemingly toward the end, with the "web" directory (probably the most important, of course!) I started getting lines like:</div><div><br></div><div><div>file has vanished: "/Volumes/mira/scsi/web/vsx/submit/qry_getRemarks.php"</div><div>file has vanished: "/Volumes/mira/scsi/web/vsx/submit/qry_getStar.php"</div><div>file has vanished: "/Volumes/mira/scsi/web/vsx/submit/qry_getVarTypes.php"</div><div>file has vanished: "/Volumes/mira/scsi/web/vsx/submit/qry_updateMethod.php"</div><div>scsi/web/zapper/</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/.DS_Store"</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/._index.shtml"</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/._zapper.jnlp"</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/._zapperButton.jpg"</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/._zapperdoc.shtml"</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/._zapperhelp.shtml"</div><div>file has vanished: "/Volumes/mira/scsi/web/zapper/Zapper.jar"</div><div><br></div><div>This is a small sample toward the end. There were hundreds of lines like this, almost as if rsync had just decided to give up.</div><div><br></div><div>I went to /Volumes/mira/scsi/web/* and I was able to determine that these files were indeed there!</div><div><br></div><div>Rsync ended with this data:</div><div><br></div><div><div>Number of files: 766415</div><div>Number of files transferred: 746551</div><div>Total file size: 66995757081 bytes</div><div>Total transferred file size: 66995737633 bytes</div><div>Literal data: 43101421090 bytes</div><div>Matched data: 0 bytes</div><div>File list size: 17422528</div><div>File list generation time: 779.208 seconds</div><div>File list transfer time: 0.000 seconds</div><div>Total bytes sent: 43129805144</div><div>Total bytes received: 16543326</div><div><br></div><div>sent 43129805144 bytes received 16543326 bytes 6411523.66 bytes/sec</div><div>total size is 66995757081 speedup is 1.55</div><div>rsync warning: some files vanished before they could be transferred (code 24) at /SourceCache/rsync/rsync-35.2/rsync/main.c(992) [sender=2.6.9]</div><div><br></div><div>============</div><div><br></div><div>I'm not sure where to go from here. The data says that 746551 files were transfered out of 766415, but I'm not even sure about that.</div><div><br></div><div>The number of bytes in the "Total size" and in the "Literal data" are confirmed by running "du" on those areas, so those numbers are right.</div><div><br></div><div>I'm not sure what would stop the rsync, or what I may be doing wrong. Any thoughts from those who've used this?</div></div><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div>---</div><div>Richard 'Doc' Kinne, [KQR]</div><div>American Association of Variable Star Observers</div><div><rkinne @ aavso.org></div><div><br></div></span><br class="Apple-interchange-newline"> </div><br></div></body></html>
