I have log shipping configured on 6 different databases for an EV SOL Server but the logshipping constantly breaks (atleast once every 2-3 weeks) with restore job Error:Could not find a log backup file that could be applied to secondary database. On investigation I found the first LSN number for the Tlog backup does not the last LSN of the previous backup that was successfully restored on Secondary.
The logshipping is configured to perform TLog backups every 15 minutes (with Backup, Copy & Restore jobs running 2 mins apart). The SQL Servers are running 2008 R2 Standard edition with SP2 (10.50.4000) on both Primary & Secondary.
We have logshipping configured on different servers and it works fine but not sure why its breaking on this server.
Has anyone encountered this type of issue before or know the reason why this LSN mismatch is happening ?
I have attached screenshot below showing Logbackups info.
