Its an all-or-nothing backup/restore. The problem there is that none of the IBM-supplied tools can interpret a Linux filesystem. You're dumping physical data, which doesn't include any metadata like what block belongs to what file. The Linux backup clients have that capability because they're privy to the information Linux keeps. That's why there's no incremental or differential capability. An image is an image. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
