That makes me wonder - how does gtar handle extended attributes? A google search didn't reveal anything definite, and the manual doesn't mention them, too. > Most Solaris users of amanda use ufsdump.

I checked on the Zmanda site, and a quick search seems to indicate that they recommend gtar and dump as choices for the actual backups. The fact that you can implant other methods using custom backup commands may make the resulting backups even less portable, I think. As amanda is built around the OS tools for backup and restore - dump and tar - it just has to work with their problems. Bacula, on the other hand, has it's own problems to handle :-) Arno -- Arno Lehmann IT-Service Lehmann www.its-lehmann.de ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
