A session for a whole day?
With previous software we released, we found that a large number of users were running multiple copies of the same software at the same time. They were doing this to help manage their data flows and keep a coordinated effort without having to re-set destinations for every source.
So what Double Data does is combine that need into one program. We now will copy that camera original source to 4 destinations. The first destination is then considered to be the MASTER, and ideally would be a high speed RAID that can read & write very fast.
From this MASTER destination, Double Data will then re-copy the footage in the secondary session to other - slower - destinations, such as single-drive shuttles or across smaller bandwidth connections such as Firewire or USB.
Double Data is even smart enough to know when to pause copy processes based on your workload. For instance, say you have a shared firewire bus for reading from the camera media to a high speed RAID over eSATA, then you want to copy to other bare shuttle drives that are on the same firewire bus. If you were to copy to all destinations at the sme time you'd get very slow results. However, Double Data can increase your apparent speed by waiting to copy to the bare shuttle drives until the data is already on your eSATA RAID. In this case you would be able to read/write at firewire's full 800Mb/sec instead of at 100Mb/sec or slower if you were reading & writing at the same time on that same bus.
Other benefits of session management
- Able to see a whole days work in one view
- Able to track a single piece of media from source through multiple copies
- Automatic pausing the second session while the first one is working
- Better management of time
- Automatic management of data throughput
- By automatically starting the second session when the first is complete, you dont waste time, or worse, forget to copy footage
- Reporting on a whole days work for editorial & archival
Or dont use session management
Double Data still does the same verified copies of your footage, to multiple destinations simultaneously. You dont have to use the multiple sessions if you dont want to. Just use the first session, and copy to multiple destinations at the same time, just like previous versions of our software.
