SQL Backup files, distinguish partial and full backup files

I have scheduled backups running through SQL Agent, with Full Backups nightly, and differential backups hourly. Is there a way to determine which of the backup files is the Full backup, and which is the latest differential?

Hyper-V snapshot backup strategy appropriate for production SQL server?

So SQL Server 2008 in Hyper-V is a supported configuration, and should perform well as long as you use fixed or pass-through disks and increase your processor/memory settings appropriately.

How to write the Mysql binary log position of master when doing a mysqldump from slave?

I am currently running mysqldump on a Mysql slave to backup our database.

If so, how? :-) EDIT: As my comment on Quassnoi's answer below indicates, this seems to be a problem for tables named starting "x-"... ...

SQL Server 2008 Auto Backup

Handle rollbacks for data edits in a multi-user environment?

How to you typically handle roll backs for data edits in a multi-user environment?

Transaction log has huge growth after backup

I am a programmer, with a side job as an involuntary DBA. I have a maintenance plan that does a full backup and a 'check database integrity' every night. I backup transaction logs every 10 minutes.

SQL Azure Backups

Has anyone come up with a good way to do backups of SQL Azure databases? The two approaches seem to be SSIS or BCP. SSIS looks like it requires a local install of MS SQL 2008 which I don't have.
