I agree with all the posts that I would prefer to back up to a directly attached disk then move the backup to a network share for Archiving. However, even after sharing all the reasons and comments from this forum and others I am always forced to backup to network shares. We have large clustered servers that host several databases making it cost prohibitive to add enough attached storage to hold our backups. There are network hiccups from time to time but our monitoring processes look for databases that have not been backed up with SLA timeframes and runs a backup if not found. We rarely have trouble with the backups to network shares even though I am not fond of the overall concept.
