Has anyone successfully run scdbackup under Fedora Core 3? I just got scdbackup 0.8.4 (available from sourceforge) and was pleasantly surprised at how easy it was to install. Then I tried saving my home directory, as per the example in its documentation. It appeared to go through all the steps until it came time to use cdrecord, when things went wrong:
TOC Type: 1 = CD-ROM
cdrecord: Cannot allocate memory. WARNING: Cannot do mlockall(2).
cdrecord: WARNING: This causes a high risk for buffer underruns.
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
cdrecord: WARNING: This causes a high risk for buffer underruns.
scsidev: '1,0,0'
scsibus: 1 target: 0 lun: 0
cdrecord: Permission denied. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
+++ failed to write backup volume
aborted

I am surprised I havńt seen more on this issue as I battled like crazy when I went to FC3 from FC1 last month - it took a lot of googling to find the answer.

When ./CONFIGURE_CD asks for the scsi address of the writer enter
ATAPI:1,0,0 (or whatever value cdrecord --scanbus gives for your writer) the important change is the ¨ATAPI:¨ stuff - voila scdbackup rides again.

Note that you must run all the scdbackup install scripts thru to ./ADD_USER to ensure all will be OK.

scdbackup is a great backup system for production systems especially in afio mode - the compression is great on standard databases.
