I want to apply the logs to the backup copy of the Exchange database. The backup was taken using the ESE Backup and Restore API (esebcli2.dll) which performs the online backup. My understanding is that, this type of logs application will be done using the Advanced Soft Recovery of ESEUTIL with /r E00 /d /I options but I am unable to do so and getting error "-528 (JET_errMissingLogFile, Current log file missing". I am able to perform the log application on the offline backup of exchange database through eseutil /r E00 /d /I but unable to do so on the backup taken using ESE Backup and Restore API which performs online backup. Here is the step by step explanation 1: Initially I performed the full backup of an exchange store with 'BACKUP_TYPE_FULL' using the ESE Backup and Restore API. 2: After some time I performed the logs_only backup of the same store of exchange with 'BACKUP_TYPE_LOGS_ONLY' using the ESE Backup and Restore API. 3: Now I want to apply all the backed up logs to the backup copy of the exchange database (.edb and .stm files). 4: For that, I placed the respective .edb, .stm files and all the respective .log files that I got from the FULL and LOGS_ONLY backup in a single folder 'E:\BackupFolder' and then renamed the last log file in the replay sequence to E00.log (as the log prefix for that storage group was E00) 4: After placing the database files and logs in that single folder, I executed the following command from that folder: ESEUTIL /r E00 /i /d The output dump is shown below E:\BackupFolder>eseutil /r E00 /d /i Microsoft(R) Exchange Server Database Utilities Version 6.5 Copyright (C) Microsoft Corporation. All Rights Reserved. Initiating RECOVERY mode... Logfile base name: E00 Log files: <current directory> System files: <current directory> Database Directory: <current directory> Performing soft recovery... Operation terminated with error -544 (JET_errSoftRecoveryOnBackupDatabase, Soft recovery is intended on a backup database. Restore should be used instead) after 1.0 seconds. Can you kindly tell me how to apply log files (backed up after some specific duration) to the backed up copy of the exchange database (the backup is the online backup, taken using the ESE Backup and Restore API). I don't want to restore the database on the exchange server; I only want to replay the log files on the backup copy of the exchange database (i.e. performing recovery only) Regards, ZQ
