All,

I am trying to backup a database of size 800 GB onto one terra byte usb drive, but this process is failing . Can anyone point me in right direction .Any help is appreciated.

I am able to backup other smaller databases onto the same drive. Also , dirve has lot of free space left on it.


Below is the log file:
SQL Backup log file 5.4.0.55

-SQL "BACKUP DATABASE I_C
 TO DISK = 'F:\Backups\d99db01\I_C_Full.sqb' 
WITH COMPRESSION = 3 "

    What was the size of the 'I_C_Full.sqb' on your thumb drive when the backup failed? What was the available space left on that drive?

    Thanks.

    I took the red gate backup for the same database , backup size was around 200 gigs ( level 3 compressions). But when I try to backup on USB drive, it fails.

    Compressed backup size = 200 gigs
    Free space on USB drive is 920 gigs.

    Thanks.

    When the error occurred, was the size of the backup file that was partially created also around 200 GB? It is helpful to know the size of the partially created file when SQL Backup failed to perform the backup.

    Thanks.

    Petey,

    Finally figured out the cause of failure.

    The 1 Terra byte USB drive was configured as FAT 32 . Later we conveted it to NTFS and everything was fine.

    Thanks .
