CRC Errors on Full Backup but not on Daily

Jeromy

 Hi,

Im kind of baffled at the minute.  

I'm backing up a site with Differential Backups Mon--> Thurs then a Full Backup each Friday.

However, the Diff Backups are working fine but the Full Backups are failing due to CRC errors.  

I've tried a new tape and long erase but still no success.

"Final Error 0x17 - Data Error (Cyclic redundancy Check)"

Any help would be much appreciated!

Hi Jeromy,
 
A full generally contains much more data than an inc or a dif. More data = more opportunity for failure.
 
Reseat/replace the cables on the tape drive and reboot everything. CRC errors are usually physical problems with the comm link. I recently resolved a similar issue by replacing a SCSI terminator.
