A transaction log backup occupies a lot less Room than a entire or differential backup and so they may be taken extra commonly. Transaction log backups will often be performed at very shorter intervals (Eg each individual quarter-hour).

Gets rid of the fractional second benefit when its scale is greater than the quantity of fractional second digits which the DT_DBTIME data type can include. After removing the fractional next benefit, generates a report relating to this data truncation. To learn more, see Mistake Managing in Data.

Eliminates the fractional next worth when its scale is bigger than the number of fractional next digits the DT_DBTIMESTAMP2 data type can consist of. After eradicating the fractional next value, generates a report concerning this data truncation. To find out more, see Mistake Dealing with in Data.
