Hi Guys,
I am reading the sync from backup documentation. In step 2, under warning it says
To avoid missing subscriber data, when using sp_addpublication with @allow_initialize_from_backup = N'true', always use @immediate_sync = N'true'.
Why do we need to use @immediate_sync? I have tested without it and it seems to not lose data as long as we have the transactions available in the distribution database.
