5.3.5 Backup Type Substitution

A full backup of the database is required before creating differential or transaction log

backups. If for some reason a full backup does not exist, you will need to create a full

backup independently of the backup strategy you have configured.

You can specify the behavior of Acronis Recovery for MS SQL Server when creating

differential backup or backing up transaction logs of databases with the Simple recovery

model:

Create a differential backup if transaction log backup creation is impossible;

Create a full backup if a differential backup creation fails – will create a differential

backup for a database with the Simple recovery model (a transaction log backup cannot be

created for such databases). A full backup will be created if the differential backup process

one fails.

If creation of the selected backup type fails, skip the backup process – the backup

process will be terminated if the selected backup process fails.
