REV drive is a nice backup for systems too large for DVD-RAM. On RedHat Linux and SCO Unix,
you can use these with Microlite
Edge, but Microlite doesn't yet support Fedora Core 2 Linux.
(added Jan 2005) Now they do:
Information about 2.6 Linux Kernel Support
BackupEDGE 02.01.01 now supports 2.6 Linux kernels. RecoverEDGE
currently does not support LVM or md software raid. Disasterrecovery
of systems using LVM or md will not function.
This release also adds support for Fedora Core 3, with the following
* Remember that FC3 has been described by Red Hat as not a
supported distribution of Linux. * Because of the frequency
of updates to FC3, support is on a "best effort" basis. While
we will make every effort to keep up with the latest patches
to it, we cannot guarantee that they will not be introduced
faster than we can qualify them.
Unfortunately, that was a system I wanted to use the REV on.
I ran into a stone wall. Interestingly, "fdisk" will create a
partition, but you can't then make any file system on it. Cdrecord
didn't work either, even though I could find references that seemed
to imply that it would. So that was it: I could find web pages that
SAID it would work, but it didn't. I made a newsgroup post, and got
no useful replies.
gave me a mountable filesystem on the REV. Fedora Core 2 already
knew how to mount a udf filesystem (though it can't mkfs one):
[root@pc-00152 root]# mount
/dev/hdc2 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/hdc1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/hdb on /mnt type udf (rw)
The Iomega REV drive isn't particularly fast: about 3GB per hour
in my tests. That's because this is more like a CD-RW or DVD-RAM
than a hard drive - udf is a packet-writing
Normally, you'd use cdrecord for such a device, but try as I
might, I couldn't get that to work. It saw the Iomega REV drive as
an emulated scsi device:

I admit to not searching very hard to try to find out what might
work because having a mountable file system was good enough for my
