Avoiding zero size dumps

disk. We have about 316 of these empty filesystems giving about 4 hours of empty backups. -- Robert MinskCentropolis Effects, LLC. [EMAIL PROTECTED]10950 Washington Blvd., Studio B Culver City, Ca. 90232-4025

Re: Not backing up file systems that have not changed

is not the slow part. The slow part is backing up filesystems than have not changed. The estimates take only about 15 minutes of the 10 hours of the backup. The tape drive spool up time for 500 filesystems is most of the time. Amanda is responsible for determining what filesystems get dumpe

of buffering and a wasted 3K of space the drive speed is about 10 megs a second. In the current version of amanda is there any way to pipe the output thru "dd" to change the block size? > John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED] -- Robert Minsk

Re: Changing tape block size

Parallel estimates

I have noticed that amanda does not do it estimates in parallel. Is this something I can configure? -- Robert MinskCentropolis Effects, LLC. [EMAIL PROTECTED]10950 Washington Blvd., Studio B Culver City, Ca

Changing tape block size

We are using a Ampex DST for our backups. It performs best when using an 8k block size. Currently amanda uses at 32k block size which ends up being about a factor of 10 slower than using an 8k block size. How do I configure amanda to use an 8k block size? -- Robert Minsk

Different length tapes

Our tape robot can handle 3 different tape lengths (165 gig, 80 gig, and 40 gig). Is there anyway in amanda to handle different tape lengths for the same drive? Would I somehow have to base the length on the amanda tape label? -- Robert MinskCentropolis Effects, LLC

Getting requested tape name in changer script

I'm am currently writing a changer script to handle our Ampex DST tape robot. Each tape has a barcode I store in a database, so I can get from the amanda tape name to the barcode number. In the tape changer script how can I find out what tape amanda is currently looking for? -- Robert
