| During a restore it may be necessary to preserve various meta data. Because, rsync is the back end backup engine for LBackup, it is possible to use rsync to restore the files to the system they were initially backed up from. Detailed instructions regarding the use of rsync are available from the [[http://rsync.samba.org|rsync home page]]. The **[[synchronizing_disk_images_between_machines|image synchronization page]]** contains information regarding coping files (preserving permissions and various meta data on Mac OS X) via the network. Finally, the **[[:developer/migrating_backup_sets|backup set migration page]]** contains information on restoring files locally between volumes. | During a restore it may be necessary to preserve various meta data.

| + | Restore times will vary depending upon various factors. LBackup makes it possible to have hot spare hardware loaded and updated with data. LBackup offers this flexibility via pre / post action script(s). Essentially, it is possible to keep a hot spare storage system prepped and ready for the restore of critical systems. This approach is particularly useful if you have a large data set being backed up and when you need to ensure that a restore time is kept to a minimum. | ||
