PORsync bash script and hard linking files
text
Body
copied!<p>I am creating a bash script to backup my files with rsync. </p> <p>Backups all come from a single directory. I only want new or modified files to be backed up.</p> <p>Currently, I am telling rsync to backup the dir, and to check the files compared to the last backup.</p> <p>The way I am doing this is</p> <pre><code>THE_TIME=`date "+%Y-%m-%dT%H:%M:%S"` rsync -aP --link-dest=/Backup/Current /usr/home/user/backup /Backup/Backup-$THE_TIME rm -f /Backup/Current ln -s /Backup/Backup-$THE_TIME /Backup/Current </code></pre> <p>I am pretty sure I have the syntax correct for this. Each backup will check against the "Current" folder, and upload only as necesary. It will then delete the Current folder, and re-create the symlink to the newest backup it just did. </p> <p>I am getting an error when I run the script:</p> <blockquote> <pre><code>rsync: link "/Backup/Backup-2010-08-04-12:21:15/dgs1200series_manual_310.pdf" </code></pre> <p>=> /Backup/Current/dgs1200series_manual_310.pdf failed: Operation not supported (45)</p> </blockquote> <p>The host OS is running HFS filesystem, which supports hard linking. I am trying to figure out if something else is not supporting this, or if I have a problem in my code. </p> <p>Thanks for any help</p> <p>Edit:</p> <p>I am able to create a hard link on my local machine. I am also able to create a hard link on the remote server (when logged in locally) I am NOT able to create a hard link on the remote server when mounted via afp. Even if both files exist on the server. </p> <p>I am guessing this is a limitation of afp. </p>
