FYI : LBackup 0.9.8r5-alpha6 has been released. It is possible to download the latest alpha release from the following URL :http://www.lucidsystems.org/download/utilities/LBackup_v0.9.8r5-alpha6.dmg Please keep in mind that the link listed above is temporary and will expire. This latest alpha release has changes within the, example_backup_config : /etc/lbackup/example_backup_config/ Once you have installed this latest alpha release, and copied the example backup configuration : > eg : 'cp -a /etc/lbackup/example_backup_config > /etc/lbackup/my_test_backup_config' You will find there is an initialization script within the resources directory : > resources/initialization-scripts/disk_images/darwin_initialize_disk_image_pre_and_post_hooks.bash Running this script and passing in the path to a disk image as the first argument, will dynamically generate the pre and post action scripts to mount and unmount the specified disk image. This is relevant to this thread because if you generate a sparse bundle either locally or on the remote SMB share, and then run the 'darwin_initialize_disk_image_pre_and_post_hooks.bash' and pass it the path to the disk image the mount and unmount pre and post hooks will be dynamically generated for this disk image. Then you may switch your backup destination to the mounted disk image and you should find that your backup will work. Please keep in mind that the 'vsdbutil' command should typically executed to enable the permissions for any backup destination partition (including virtual file systems) provided you have access to an admin account. Further details are available from the following URL : http://www.lbackup.org/permissions The longer term goal of the initialization sub-system is offer a number of ways to automate the creation of a backup configuration directory and also the a backup destination (disk image). Should you have any questions, comments or additional initialization scripts to submit to the LBackup project then just reply. _______________________________________________ lbackup-discussion mailing list http://www.lbackup.org Change options or unsubscribe : http://lbackup.org/mailing_lists
