How does SD manage out of diskspace on a Time Machine disk
First congrats on the new release!
Next question: What happens if I use the same volume for Time Machine and a SD clone and Time Machine uses so much disk space that the clone doesn't fit anymore? Does SD throw away enough old Time Machine backups to free enough space? Or does it simply complain about not enough disk space. Time Machine will eventually fill the disk so I hope SD can cope with that. |
It'll just complain, so make sure you have sufficient space...

Unfortunately, given the way TimeMachine works, every disk, regardless of size will eventually fill up. It seems to me that the only way to guarantee space for a SuperDuper clone on a TM disk is to partition the disk to guarantee enough space is reserved. I know you added the feature of having an SD clone and TM backups co-reside on a single disk to make life easier for the non-technical user, but you may have created a larger downstream problem. To ensure space for a maxed out source disk after TM has claimed "too much" space on the backup disk will require the user to manually delete selected TM snapshots. (I believe that is possible but I'm not certain it is.) For a non technical person that is scarier and more difficult than partitioning in the first place. Assuming your users read manuals and FAQs you may want to make note of the issues involved when you update the manual and the FAQs.

Yes, I'm definitely aware of the issue.

SD can't complete; Time Machine filled the disk
I just ran into this problem. SD 2.5 cannot complete a back-up because TM has filled up most of the drive.
Do you have any advice on how to back-up until I buy another drive? Is there a way to reduce the space that TM uses? If so, I can't find it. Thanks, Marc |
There are a few things you can do. If you have a particular large file that's eating space (e.g. Entourage database), you can go into Time Machine, select it, and use the Action Menu in Finder to remove that file from all your backups.
You could also turn off Time Machine and remove some of its backups or all its folders... |
Maybe SD could propose -as an option- to remove some of the oldest TM backups as TM does, to get the required space to finish it's own backup? (don't know if this is easy to do, and if Dave considers SD to be allowed to interfere with TM though)
|
It's not something we can do, actually: there's no API for it. If it's something you're worried about, you should store your SD! backup on its own partition...
|
Yep, that's what i did. But it was worth asking... I didn't know if Apple had published the TM APi or not.
|
There's an API but not for this kind of thing.

Yes - it's the "Gear" menu in the toolbar.
