Our database backup was running ok for the passed 3 months after the SAP system was installed. Recently, I keep getting BR278E error during backup. Below are the error message:
BR0202I Saving init_ora
BR0203I to /dev/rmt/0mn ...
BR0278E Command output of 'LANG=C cd /oracle/PRD/102_64/dbs && /usr/sap/PRD/SYS/
exe/run/brtools -f printarg initPRD.ora spfilePRD.ora | LANG=C cpio -ovB > /dev/
^GEnd of medium on "output".
To continue, type device/file name when ready.
The SAP system is on Solaris/Oracle running ECC6.0. LTO-4 tape drive is used for the backup. Tape_size in initSID.sap is set to 720000M. Current database size is 128Gb.
What is the reason for the backup failure?
