 Description  « Hide
Ability to compress nbackup output on the fly helps to save both backup time and avoid need in disk space for intermediate uncompressed files:
nbackup -b 0 employee stdout | bzip2 >e.b0.bz2
nbackup -b 1 employee stdout | bzip2 >e.b1.bz2

Unforutnately that trick does not work when restore is needed cause a set of uncompressed files is required for utility:
nbackup -r e.fdb e.b0 e.b1

It would be great to make nbackup decompress files on the fly one by one, without wasting resources for intermediate files.
