We ignore files generated by other backup plugins, cache files, and log files as they do not add any value to the backup. Backing them up would put unnecessary strain on your site and also cause issues at the time of restore. You can get the list of skipped files by clicking on the Skipped Files button.
These files might be skipped because they might not have been changed since the last backup, or they might add no value (such as cache files), in which case backing up these files only adds to the size of the backup. BlogVault skips files intelligently, without compromising the value of your backup: they contain all the information on your site, while also efficiently managing the backup storage space you subscribed to.
