ERASEFILES dosen't erase files...

With the below script, I backup one of our databases, it mirrors the backup to a standby server and also copies to a backup file server. I got tired of cleaning out the old copies on the backup server and after re-reading the help file discovered the FILEOPTIONS parameter, however instead of actualy cleaning up the files at the local, standby and backup servers it now doesn't erase old files at all. A slight variant is backing up multiple database and specifying two COPYTO locations, with one COPYTO , the FILEOPTIONS parameter was being honoured but with two it isn't.

EXECUTE master..sqlbackup N'-SQL "BACKUP DATABASE [db1]
TO DISK = ''F:\sqlbackup\db1\db1_db_<DATETIME yyyymmddhhnnss>.sqb''
MIRRORFILE = ''\\mirrorserver\shipping\SQL2005-1\DB1\db1_db_<DATETIME yyyymmddhhnnss>.sqb'',
COPYTO = ''\\backupserver\sql2005-1\db1\'',
MAILTO = ''[email protected]'',
MAILTO_ONERROR=''[email protected]'',

    FILEOPTIONS=7 includes the option to only delete copied backups when the archive bit is clear. If you look at your backup folder in Explorer and turn on the list view, this should show an A on all files that have the archive bit set; these will not be deleted.

    You mat want to set FILEOPTIONS=5 to ignore checking the archive bit.
  • Doh, I feel like a goober. Dunno how i missed that, but rereading the docs, it makes sense
