Yes, I suppose that question has an obvious answer- turn it off via the "silent mode"- but, sometimes the obvious answer isn't right, so I ask here.

Pat L,
hmmm.... now that I think of it-- that Norton "task" of defraging disks is suppossed to come on only when the system is idle... so if a backup is occuring, I should think that's not considered being idle, but I'm not sure-
If I'm doing the backups at night via the schedule- I won't be there to turn off the PC Tune Up in Norton, so I hope it doesn't come on if the system is being backed up.
I'm going to try this on my old PC.

well, I found out that Norton tune-up does come on while ATI is doing a backup-- to bad, so I suppose I'll need to set up the tune-up to come on only when I trigger it
a similar concern- what if Microsoft updates start occuring during a backup? I do have the updates set to automatically download them- I suppose this isn't as big an issue as disc optomizing turning on but those MS updates can be huge and I don't know how ATI backup program will deal with them
too bad ATI can't just turn off any such activity which might mess up the backup- or, am I being a pessimist about this? perhaps the backup will go OK regardless?

An update occurring during an image whilst not ideal shouldn't be a problem as True Image uses disk snapshots to make images.

Colin, just curious, but-- what is a "disk snapshot"?
and, as somebody mentioned in a different thread, the backup doesn't check for changes in files, it checks for changes in sectors- so, I'm also curious how it does that- are sectors given dates when written to?
I suppose some people just use programs like Acronis and don't think too much about it- but, this is a powerful and complex program with a huge user guide, and I have enough of a minimum understanding of programming that my curiousity keeps me asking questions.

hmmm.... now, that question was in regard to the use of T&D- that a defrag could mess up the file system--- but, what if I wasn't using T&D, just doing a backup?
There must be a lot of people who use something like the auto tuneup facility within Norton AV, which can defrag drives after a certain idle time--- if that kicks in while a backup is occuring, I hope it can't damage the file system- even if it does result in a much larger backup
Joe
Joseph,
At the beginning of a backup, ATI takes a snapshot of the sector information, redirects the following disk write requests temporarily, completes the backup operation, then applies the pending changes to the disk.
So, in theory, you don't need to worry about operations during a backup, except for performance impact.
The other issue is that a defrag operation can be sector-level change intensive, although there is not change in the information in the files themselves, so that creates a lot of changes for ATI to backup. As a result (a) ATI needs space to hold off the pending request, (b) the next backup will include all the sector changes resulting from the defrag, so it will be bigger than necessary.
Pat, thanks again- it's great to be able to learn what's really going on from experts like you.
Amazing that ATI redirects disk writes temporarily- so, in theory, we could continue working without much worry- at least for routine work such as MS Office stuff. I also sometimes do video work and those files are huge so I wouldn't want to work on those- even though I have a second internal drive for video work- that work is CPU intensive, so best to skip video work during backups.
So, again, it seems that it's best to turn off my Norton automatic tuneup feature- or at least turn off the defrag feature, if I'm going to use the scheduler to do backups in the middle of the night, as it seems that the tuneup does turn on, though it's suppossed to turn on only when the system is idle and the system isn't idle when doing a backup- apparently a system idle means I'm not doing anything with the mouse or keyboard. But, I hate to turn it off- so, either I turn it off, or I don't use the scheduler and choose to turn on the backup manually after turning off the tuneup feature temporarily. I suggest that some mention of this issue should be in the next version of the user guide- in case any Acronis people are reading this. :)
