fbackup - How do I?

[ajsobers]

How do I copy the contents of two source directories directly to a compressed file on tape.

I'm thinking:

fbackup -f -g /my_graph_file_location | compress > /dev/rmt/0m/FILE.Z

The contents of my graph file contain two entries:

-i /source/dir/location/1
-i /source/dir/location/2

hi,

-f specify your destination

so you can use -f /dev/rmt/0m
For compress, i don't know if you can use | compress

I would be wary of running the backup thru compress. I can be done, but:
1) most tape drives today have hardware compression anyway. If you feed such a drive "compress"ed data, you may actually use more tape than if you didn't.
2) it may slow down the ability to selectively recover files. (see the man pages for fbackup regarding separator marks w/ DLTs)

If your goal is to increase through-put, see Bill H's config file recommendations in this thread:

Ok, maybe I'll skip the compress part and just copy directly to tape. Now I have:

fbackup -f /dev/rmt/0m -g /graph/file/dir

Hi again

Add -I "path" to have an index
Files saved are specified, with size etc...

It will be interisting to debug

Aren't the two lines:

-i /source/dir/location/1
-i /source/dir/location/2

inside my graph configuration file enough?

Are you saying that I have to include it (the i, option) at the command line as well?

Hi:

you are confusing '-I path' (an uppercase "I") with "-i path" (a lowercase "i"). The uppercase switch is for creating an index file. The lowercase switch is for including a path and as you know can be a '-g'raph file specification, too. See the manpages for 'fbackup(1M)'.

Regards!
