Does DBMaker remove existed incremental backup file after next full backup? (DBMR1968; Version: DBMaker 4.3.4 bundle)
Before 5.0 not including 5.0, DBMaker never removed existed incremental backup files in DB_BKDIR. But user found these incremental backup files is useless after a new full backup (MR 8121).So we remove previous useless incremental backup files after a new full backup on DBMaker 5.0.
No matter you set DB_BkOdr keyword or not, 5.0 must remove previous incremental backup files in DB_BKDIR. If set DB_BkOdr keyword, previous incremental backup files will be copied to DB_BkOdr. It means 5.0 will remove or backup previous incremental backup files before doing the last full backup.
5.0 do some change for backup, for detailed, please refer to related manual.
