[lbackup-discussion] LBackup Question

[henri]

Assuming you are backing up to a network based file system then the following information will be helpful.

FYI : The most recent alpha build of LBackup includes the following output (quoted below) now when the permissions are detected to be disabled on the destination. 

> Check that the destination file system is directly attached storage or is a virtual file system.  Network based file systems are unsupported backup destinations (for LBackup backup sets).

You may store the backup on a network attached file system if you use a virtual file system. For example on Mac OS X you may use a disk image. The following page contains information relating to encrypted backups : http://www.lbackup.org/encrypted_backups

Please note that you may also generate disk images on Mac OS X which are not encrypted and the information found at the URL(s, above and below) will be relevant.

Also, if you are using the latest alpha release of LBackup then the following page will be of interest to you should you decide to use a disk image as the backup destination : http://www.lbackup.org/initialization_scripts/initialize_disk_image_pre_and_post_hooks

You may wish to download the most recent alpha build from the following URL : http://www.lbackup.org/download/latest_alpha_release/

Best regards,
Henri

>>> Checking the file systems (source and destination) should be fine. However, I would suggest that before you attempt to repair any file system(s) you should first make a sure you have a up to date backup of any important files. If the hardware is failing then attempting a repair could make the volume(s) un-mountable.
