The problem is that i have a backup tape drive (Seagate STT38000N) with a capacity of 4GB uncompressed and 8GB compressed. But it does not seem to support hardware compression (at least i couldn't enable it with 'mt comp on'). And on the other side there is a hard drive that has to be backuped by this tape. The uncompressed data which has to be backuped will be approximately 3-6GB. Now im looking for a way to do some software compression on the data so that it fits one tape. That way it can be done by a nightly cron job. As far as i have read in the archives and in the manpage, dump (which seems be the best backup tool) does not offer any compression at all. Right? Tar with gzip does not work either for me because the lenght of the pathnames exceed 100 characters sometimes and tar cannot handle that long pathnames. Does anyone know any other way to do some sort of software compression for tape backups?
