Excessive snapshot size causing failure

    Question

  • Hi,

    I am searching for an explanation of a replication snapshot being in excess of 5 times what we're predicting

    Following a replication failure we are attempting to reinitialise subscriptions with a new snapshot. The size of the database is 135GB, one table within the database is 60GB - we have excluded this article from the publication. This meant we had an expectation of snapshot size being ~75GB.

    We've had several attempts at creating the snapshot and these have failed due to lack of disk space. Last night the snapshot filled a disk with 340GB of free space.

    I 'd welcome any explanation for this huge size of snapshot.

    In my examination of possible causes I note that the snapshot format is set to "Character - Required if a publisher or subscriber is not running SQL Server". This despite the fact that at both ends of this transnational replication  is native SQL Server. Is there a different in size between formats?

    Thanks in advance.
