SBS Backup

[josh2009]

hi,

I created an sbs 2008 scheduled backup on to a spare hard drive in the server. on 9th July. The first job took five hours and all jobs since then have been incremental, taking 30 minutes. On 16th July, the scheduled job ran as a full job rather than an incremental one, taking 5 hours.

Why would this happen?

Are you sure you didn't swap drives?

Or did you do a defrag on your drive before July 16th? Something that would have changed the locations of everything slightly on the block level?

No defrag. I restarted the server on 13th. The backups on 14th and 15th were both incremental.

the scheduled backup ran last night as a full backup, not incremental. Is this by design where a full backup is taken once a week, with the rest being incremental?

 

[ShackDaddy]

The first job on any media will be a full backup. Any additional backups to the same media will be an incremental, forever. If you took a media out of rotation for several months, when you put it back in, you'd still have an incremental run against it, but it would be pretty large. So if you put in a new disk, you'd have a full backup. Maybe something happened to the disk that caused it to be recognized as new media.

Are all the backups you are talking about done through the SBS Backup wizard, or did you set them up in some other way?

There is one scheduled backup job created using the sbs 2008 wizard.
