dump database adds a cyclic redundancy check for accidental
changes to raw data for database or transaction dumps created with compression to check and
for verification that the compression blocks can be correctly read and
decompressed
The syntax
is:
dump database database_name to dump_device with compression=n,verify={crc | read_after_write}
Where:
- verify=crc – indicates that you are performing a cyclic
redundancy check.
- verify=read_after_write – Backup Server rereads every
compressed block after writing and decompressing it. If Backup Server finds an
error, it prints the offset in the file it finds the error. You cannot use
verify=read_after_write with load
database commands.
