flexbackup compression question
« on: March 22, 2003, 06:25:29 AM »
Hello all,

I have a Seagate Hornet STT28000A tape drive.  It uses the Travan 4/8GB tapes.  This is supposed to be able to backup up 8GB of data compressed.  How can I ensure that compression is enabled.  I have more the 4GB of data on my system and now my backups are failing.  I went into flexbackup.conf and changed the compression from 4 to 9 under the gzip section, but that didn't help me.  Is flexbackup not really compressing files?  Short of buying a new tape drive (I hear you), what else could I check?  

Thanks,

JB

Remember that compression is not always available. If all your files are jpgs eg. then you won't be able to compress them anymore as the jpg format is very compressed in it self!
Files such as tiff and mdb can be compressed very much but if they already are compressed/zipped then the compression on the backup won't give you the double space as you should think it would do!

Yeah Michael, I know this.  I was just further confirming that I seem to be getting all out of my tape drive that I can. I had messed with the compression settings and things got a little better, but not good enough.  Thanks for taking the time
