i am getting the following error when i try and restore a datbase
The log in this backup set begins at LSN 110000000011300001, which is too late to apply to the database. An earlier log backup that includes LSN 102000000188100001 can be restored..
Presumably you restored a FULL backup, and then you have restored zero, or more, TLOG backups, and now you are trying to restore a TLog backup. The message indicates that you have missed a Tlog backup in the chain.
You can check the Backup History to see which Log backups were made.
