tape backup tool ?

[Dmitry Melekhov <dm@xxxxxxxxxx>]

Hello!

We run xfs on our backup server, and I want to store ACLs to tape too.
I decided to use star, because it supports ACLs and it allows to restore 
single file.

I wrote backup to tape with following command:

/usr/bin/star c --file=/dev/st0 -acl -H=exustar ./


But when I  try to restore sometimes star can restore acls:

backup:/BACKUP/test # star -x -acl -H=exustar --file=/dev/st0
star: current './' newer.
star: Invalid argument. Cannot set ACL 
'user::rwx,group::rwx,group:belbank:rwx #effective,mask::r-x,other::---' 
for 'apps/belbank/BACKUP/client/'.
star: Invalid argument. Cannot set ACL 
'user::rwx,group::rwx,group:belbank:rwx #effective,mask::r-x,other::---' 
for 'apps/belbank/BACKUP/client/1/'.


Any ideas?

Or, may be, someone knows better tool for tape backup?

Thank you!
