I have backup problem of redhat 7.2 with ext3 file system. I'm using dump for backup. The problem is one of the filesystem (/proj) Incremantal backup is not happening. The command used is dump -u1a -f /dev/st0 /dev/md0 Daily its taking the entire file system backup eventhough i tried incremental. This is happening only for /proj and proj1 is working fine. Filesystem Size Used Avail Use% Mounted on /dev/md1 8.1G 3.4G 4.3G 44% / /dev/sda1 48M 14M 31M 30% /boot /dev/md0 39G 29G 7.7G 79% /proj /dev/md2 16G 13G 2.4G 84% /proj1 none 262M 0 262M 0% /dev/shm Backup Device : HP SURESTORE DAT40 Dump Version : dump-0.4b28-1.i386.rpm Regards, Rajeesh Kumar M.P System Administrator Aalayance E-Com Services Ltd, Bangalore - India

If you use dumplevel 1, dump will perform a dump of everything that has been changed since the last level 0 dump (NOT since the last level 1). If you've never done a level 0, then every level 1 will be a full dump. --Stephen
