We often use ZIP and then BACKUP (in OS2) to backup our hard disk 
but have encountered excessive number of CRC errors while RESTORing the 
backuped disks. Is this a known problem with the use of ZIP and BACKUP ?
Generally our ZIPped files are over 10MB and therefore requires at least
a dozen of 3.5 HD disks (sometimes over 20 disks!!) to BACKUP the archive 
file.

Any suggestion on backuping a very large zip file ? Any alternative 
(from ftp?) ?

We also have access to ZOO, ARJ and LHA but have not used them as serious
as above.

Please respond to eric\@cs.su.oz.au as I do not subscribe to this group.

Do you have any OS/2-port of arj ??
I only found an unarj which should support HPFS but i didn't if it does so...
