fbackup/frecover to disk compressed

[David B. Bordwick]

Is there any way to fbackup to disk in a compressed format either with a special device or pipe to the compress utility? If so, how to frecover the compressed files? Thanks.

Hi there.
Try this for backup :

mkfifo /xxx/gzip_pipe
cat gzip_pipe > /xxx/backup.gz
fbackup -f /xxx/gzip_pipe .....


restore :
mkfifo /xxx/gzip_pipe
gunzip /xxx/backup.gz > /xxx/gzip_pipe
frecover -f /xxx/gzip_pipe .....

Hi there.
Forgot one thing.
Run the cat statements as abckground processes.

fbackup and frecover (like a lot of other commands) allow the use of -f - which specifies standard input/output as the file to operate on.

Thus you can do:
fbackup -f - | gzip >
gzcat | frecover -f -

Note that other arguments to fbackup and frecover are required. 'gzip' tends to compress better than 'compress' and the use of gzcat means that you don't need to unzip the file to use it thus saving diskspace.
