Hi,

We have a Sun Unified Storage 7410 system with 16T disk capacity that we want to backup via NDMP over 1Gb LAN. Our Netbackup 6.5.4 backup server runs on Solaris 10 on a Fujitsu Primepower 450 and has a fibre attached Quantum PX 506 LTO tape library. Two drives are used for this policy.

We have a backup policy vor each volume. Example:

/export/adnorbck    0.6 T   (mostly large files, 19784 inodes)
/export/archive        1.1 T   (many small files, 12672510 inodes)
/export/backup        0.9 T  (mixed small and large files, 896027 inodes)

The volume /export/adnorbck is backed up fine with a mostly constant speed of about 60 MB/s. But the volumes /export/archive and /export/backup have very slow write performance (ca 6 MB/s). We tried to back up the volume /export/backup twice but every time it seems to stop at the same position (330361290 kB and 12000 files written). The backup status says:

We cancelled the backup at 07:01 because nothing is written.

Does somebody have a clue what is going wrong here?

Thanks in advance for help.
