Time Machine and Excel Missing File
An important Excel file of mine just disappeared both on my hard drive as well as on my Time Capsule backup, which is really puzzling me. Here are the facts:
1. I am using an iMac, running Mac OS X 10.5.8, with Excel:mac 2008 version 12.2.7. I religiously update both my OS and applications, so they are both up to date
2. Within Excel, if I go to File/Open Recent, there is a dropdown of recently opened files. The missing file is shown there but the "xlsx" tag is missing on that name, oddly. The other files (which are all still there) still have the "xls" or "xlsx" tag. When I click on that file, I get that error message that the file cannot be found
3. I then opened up my Time Machine on my Time Capsule and went scrolling back in time, and really weirdly, this file is missing in every version of backup. My Time Machine has the default backup of hourly for the past 24 hours, daily for the past month, and weekly before. I went into the folder where I kept the file all the way back to July (when I got the Time Capsule) and this file is missing from EACH backup. All other files are there.
I work on this file every day and I tend to keep it open on iMac. Usually when Excel crashes or something, it reloads with a recovered version but Excel hasn't crashed recently. I worked on this file as recently as yesterday and saved it in the same place where I've been saving it for the past several months.
OK, what's changed from yesterday to today? Last night when I updated my software there was an update from Microsoft for a security patch. Could it have detected a virus in this file and deleted this file from my hard drive and then from each and every backup in Time Machine?
The second change was that I selected "Back Up Now" for the first time on Time Machine last night after that patch. I usually had Time Machine run automatically, but while I was updating, I decided to do a forced backup. Could this forced backup have deleted all prior instances of this file if it was missing on my hard drive then?
This file is important to me, does anyone have a suggestion as to how I can retrieve it? I thought having Time Capsule would save this kind of headaches. I did a search within the backups, in case the file mysteriously "moved", but the file is just plain missing on all backups and on my hard drive. To make things worse, I Emptied my Trash last night, so I can't see if it is in there. Though, I didn't delete the file.
Thanks for any help!
