we have SharePoint enterprise 2013, and i run the following command to do a farm backup:-
Backup-SPFarm -Directory \\****\backups\ -BackupMethod full -BackupThreads 10 -Force
now on the generated backup folder i got many .bak files ranging from 2kb size to 10 GB... also i have noted that for our sharepoint sql databases the "Last Database backup" date will be updates as follow:-
so can i conclude that the
Backup-SPFarm will mainly do a pure sql databases backups ? also what are the .bak files which have small sizes such as 3 kb ?
