I am attempting to do a full backup of server 2003 SB and I keep getting an error reading a partition "Could not access portions of directory F:\."  Below is the log file information.  Any suggestions based on the log?  Just says can't read the backup to verify. Do the incremental backaups and the full have to be named differently or the same?

if i'm reading this correctly, you have over 200,000 files at over 300Gb total but when the backup fails it shows 3 files backed up with 1 corrupt but the total data is 154Gb, so basically you have 3 files that add up to 154Gb.  that may be your problem.  also make sure that you are not causing recursion by placing your backup copy in the same location that you are backing up to.  i would check to see if you indeed have a 3 files that add up to 154Gb or so and see what's up with that.  i don't think ntbackup has any limits on file sizes other than what ntfs is restricted to which i believe is around 2 to the 64th bytes.  if you indeed do have one file at that size then i would check to see if it is legitimate cause single large files cause problems even if the file system can handle it.

Thanks!  I think the backup is backing up the backup drive. I may have to redo the backup scheme. Can you confirm if the backup Incremental and full have to be different names?

in ntbackup, you have the job name and then the backup file name.  i think it's good practice to keep the incremental backup separate than the full but i believe ntbackup will append to a single backup file in either case.  

just a note on the side, make sure you have a purpose for your backup......meaning you have a goal in mind that you are trying to accomplish, for example to not lose anyones files or to recover the system in case of a major malfunction.  after you have a purpose it's a good idea to test to make sure you can achieve your goal in case reality strikes, always have a disaster recovery plan and execute it on occasion so you'll be ready just in case the drill becomes reality some day.

if you are using the backup for file restore only in case of deletions and such then you may want to implement shadow copies along with your backup structure.

Thanks! I have shadow copy enabled on it. I never tested the backup if they work actually. Considering they don't have me on retainer.  I just want to make sure the backup is backing up.
