I have huge iPhoto and iTunes catalogs. This can present a problem for both loading the applications and for backup. I have learned to deal with the Application load times, but backups are very important to me.**I’d gone through the iPhoto backup process and restore more than once, and I didn’t like the fact that I didn’t have an offsite backup, so I paid for a flickr pro account ($24/yr, supports iPhoto export and RAW format). I had been simply copying my iTunes over to my NAS for a long time (as well as using Time Machine), but that became a chore because I had not automated it. After about a month of off-and-on searching, I finally went back to my UNIX roots and decided on rsync.You simply can’t beat rsync.I wrote a very simple shell script to call from cron every night to sync whatever IU thought I needed to sync to my NAS (it works to any other source, really, due to rsync’s flexibility).This is my simple rsync script:
#!/bin/sh# Sync catalogs to externally mounted volume.# nick@buraglio.com RSYNC='/usr/bin/rsync’ITUNESSRC='/Users/Shared/iTunes' # iTunes FolderITUNESDST='/Volumes/Volume_1/Catalog\ Backups/iTunes' #Destination for iTunes BackupIPHOTOSRC='/Users/Shared/iPhoto' #iPhoto FolderIPHOTODST='/Volumes/Volume_1/Catalog\ Backups/iPhoto' #Destination for iPhoto BackupPARAMS='–ignore-existing –delete –progress –recursive –perms –times –size-only –whole-file' # Any parameters for rsyncEXCLUDEITUNES='-exclude='.' -exclude='.m4v'' # Files or folders for exclusionEXCLUDEIPHOTO='-exclude='.*'' # Files or folders for exclusion $RSYNC $PARAMS $EXCLUDEITUNES $ITUNESSRC $ITUNESDST $RSYNC $PARAMS $EXCLUDEIPHOTO $IPHOTOSRC $IPHOTODST Thats it. Since the “–delete” flag is in place, I recommend use of the “–dry-run” flag the first time to make sure it does what you want, since delete will remove everything in it’s path and make the folder match. I just have this run from cron every day using this line in my users crontab.
