Error message for sql backup size

[cheryl_gc]

scj/backup/scj_pro_49.2013-08-07.sql is sql but size is only 795

What size should the backup size be?

scj_pro_50.2013-08-07.sql 797b

Yes, for some reason it doesn't write to file
make sure you have all updates and if you want me to investigate this problem - pm access to ssh
