Time Machine can be used to retrieve individual files, or even previous 
versions of files that still exist. You can also use Time machine to 
open the old files to copy text or whatever from them without fully 
retrieving them. Individual files can be retrieved from Time Machine in 
the Finder, or opened from Time Machine in whichever app they were 
created in (assuming the developer has included that functionality of 
course).

The biggest "problem" with Time Machine is that is does store multiple 
copies of files when they have been changed, so it takes up more space 
than a simple syncing back (it's the same issues with Apple's silly 
"Versioning" system, which is a pain in the backside!). That's why I 
don't use Time Machine and prefer Carbon Copy Cloner. Most syncing 
backup apps can be set to keep copies of files no longer on the source 
drive, which would help in your situation even if another sync has been 
done since you emptied the Trash.

Thanks, Your Name.

How old are the files that Carbon Copy Cloner can retrieve?

(Super Duper has already updated my back-up drives' contents to clone 
my Mac's contents, since I set it to back up my Mac every night, so the 
file I want to retrieve has been wiped off of those back-up drives 
also).

Carbon Copy Cloner has three options:

   - Safety Net On
     Keeps copies of files no longer on source drive in a separate folder
     (not the original location) for as long as backup drive space allows.
     When backup drive space is running out it will delete the oldest
     files first. (Time Machine has a similar technique.)

   - Safety Net Off
     Does not keep copies of files no longer on the source drive.

   - Don't Delete Anything
     Keeps copies of all files forever (or until manually deleted from
     the backup drive). Backup drive will eventually run out of space.


I've never used Super Duper, but it may have similar options.

No, not at all. Time machine takes a snapshot periodically (the default is 
every hour) of the state of your filesystem, saving *changed* files. Going 
"back in time" shows the files and changes that happened vs. time. I've used 
it to recover individual files or directories but it can be used as you say 
-- to recover an entire system once it's been cleanly installed on a wiped 
disk.

Backups are a curious thing. People don't think they need them until they do. 
Then get upset when they're told "just restore from your backups or type it 
in again".

I use Time Machine and a cloning tool (SuperDuper!) to create an entire copy 
of my disks once a day. Time Machine runs every three hours. Backups are a 
multi-level thing, really. NEVER depend on just one.

If it's to much trouble, then you should start typing. You've got a lot of 
work to recover. I really have no sympathy for you.

Super Duper apparently does not backup the recovery partition, but 
Carbon Copy Cloner does.

So you restore versions until you find the one you want.  It's slightly 
tedious, OTOH, maybe you shouldn't be emptying your trash so often or 
quickly.  You can get free utilities that automatically empty your 
trash, too, after a period that you set.

Time Machine automatically makes hourly backups for the past 24 hours, 
daily backups for the past month, and weekly backups for all previous 
months. The oldest backups are deleted when your backup disk is full.

No.  Just those files you elect to restore.

Many of the "file recovery" utilities rely on the system being quiescent 
between the time you delete something and when you attempt to recover. Files 
may be recovered in whole or in part. But, unless you backed it up, you're 
rolling the dice here. Disk Warrior, Tech Tool Pro, etc. all used to sell 
disk recovery utilities. Some still do. I have no idea how good they are with 
the new disk format.

You want it back and don't want to use Time Machine, try a TARDIS instead.

alsoft, the makers of diskwarrior, never had a recovery utility. what
diskwarrior does is repair directory corruption.
