Has anybody used the buffer program to speed up tape backups? I have
tried it on tar backups to my scsi-2 travan-4 drive and it either
doesn't change the backup rate or actually slows it down.
I am calling using a command like:
tar --gzip --create --file - / | buffer -o /dev/nst0
I played with some of the options for buffer without much improvement.
I guess I was a little disappointed with respect to its claims and its
actual performance. I would like to speed up my backup, as it is now a
backup of my system containing about 5.5Gigs takes almost 5.5hrs. That
is only about 275k/s transfer rate which is way below the capabilities
of the drive. Which leads me to believe there can be improvements on the
software side of my backup.
Thanks,
