Availalbility Group Error

  • Hi Experts,

    We are getting below error in our secondary replica.

    The mirror database, "Financials", has insufficient transaction log data to preserve the log backup chain of the principal database. This may happen if a log backup from the principal database has not been taken or has not been restored on the mirror database. (Microsoft SQL Server, Error: 1478)

    how can i resolve this?

    TIA

    As for some extent I know, u need to take full backup and a log backup as well on principal instance. Copy full and log backup from principal to mirror instance. On mirror instance restore full backup database with NORECOVERY option. On mirror instance apply log backup and then start synchronization on principal instance.

    Thanks jacksonandrew321,

    so basically need to start from scratch. How about recreating the same with 'Full' option?

    It looks as though data movement has been suspended to this secondary, check the AO config health and look for any errors
