If the reading process or the recovery process fails, the database will not be brought online and will be marked as Suspect or Recovery Pending , based on the failure stage. If any hardware issue detected, contact the system administrator or the hardware vendor to fix the issue for you.
If the issue is caused due to a Transaction Log file corruption, continue reading this article to know how to fix that issue. The best and the safest option to fix the database Transaction Log file corruption issue is restoring the database from the latest backup chain, that includes restoring the Full backup, The Differential backup, and all Transaction Log backup to the last healthy point in time before the corruption occurred. But what if this option is not applicable, due to having no proper backup strategy configured or some of the backup files in the current backup chain were lost?
In this case, we cannot accept the data loss that is resulted from restoring the last Full backup file or half of the backup chain before reaching the lost backup file, as the database contains critical data.
The last applicable option, that deserves trying is rebuilding the Transaction Log file, as we will show in the next section, tolerating the lost of recovering, undo and redo, the transactions that were located in the original Transaction Log file.
Backup the full database. Restore the full database which has been taken before the trucatation. Restore the last full backup after truncatation. My question is, am I in Right track or not. Please suggest. What should I do? Thursday, March 24, AM. No, I do not think it is OK I would set my db to FULL recovery mode and have a full backup at midnight and then backup log file every hour, so if disaster happens I will restore FULL backup from the midnight and then apply all log backups till point of failure create database test GO create table test..
The question you should ask yourself is: Do I need to take log backups. Checdule regular log backups, since a log backup will empty your log. Set the database in simple recovery model. Can you tell me how do I get this log file to shirink? TIA, Joe. Sunday, July 10, PM. Joe Yes , mirroring may cause to the log file to grow.
