Hi there ! I am running a RedHat 6.2 under a I'd like to make tape backups under a HP, AIT 50/100 tapereader, the problem is I can't find drivers for linux and I'd like t know if one of you managed to have this kind of tapereader work normally... Thanks. -- Asega Adrole asega@-SPAM.MY.***-aliacom.fr http://www.xunix.org/~asega http://www.aliacom.fr

You shouldn't need any drivers if it's a SCSI Tape unit. Unlike Win/NT, all tape drives basically operate in a similar way, and there is a standard for accessing them that all Unix systems use. You basically talk to it using a stream device.. Usually it should come up as /dev/st0 (SCSI Tape Zero).. /dev/nst0 is the non rewinding device (Normally it will rewind when you close the file).. A simple way to test is this :- cd /bin tar -cvf * /dev/st0 This will TAR up the files in bin and write them to the tape.. The tape will then rewind.. to get a listing back do this :- tar -tvf /dev/st0 this should print a directory listing for the files on the tape. You can also use "cpio". If you need a simple to use backup script, I recommend mine which is on http://www.linuxhelp.com.au/free.shtml It's called generic-backup.sh, it's a shell script that will backup the partitions you specify, rewind the tape, verify the tape contents, and if it's a good backup, eject the tape. You can then make it automated from cron, so all you need to do each day is put the days tape in the drive, and in the morning, if the tape is back out, you know the backup was good. -- Anthony Rumble - Managing Director EverythingLinux.com.au - The Alternative Operating System Store LinuxHelp.com.au - Support,Training,Development,Consulting Phone: 0500 500 368 Direct 02-9712-1799 Fax 02-9712-3977

do the linux 2.2/2.4 series kernels have a 2/4gb limit on tape sizes? was wondering as an application called taper which is a really excellent app for tapes claims it can only do 2 or 4gb (cant remember which) and was wondering if its an app limit or kernel...

Thats a new one on me.. I don't believe there is any real limit.. as it's just a streaming device.. you output to it.. Kinda like asking.. "Does a Terminal/TTY/Serial Port have a 2 Gig limit".. I've certainly used tapes that are far larger than 4 gigs. Perhaps it's a "taper" issue?
