Anyone recovered BaseCamp data successfully with Time Machine?

In addition to enduring the limitations of the current temporary fix to allow BasceCamp Mac run under Big Sur, my 1-year old iMac runs incredibly slowly, no matter the application. It has been like this both before and after moving to Big Sur. So, I am considering a clean install of Big Sur, erasing my iMac drive and copying my data back from my Time Machine backup in hopes of speeding things up  

I nosed around on my TM backup disk, and feel good about the data for most applications, but noted that none of the Application Support files for BaseCamp (or for any other applications) are visible on that disk. That would be the folder that includes all of my waypoints and tracks.

Has anyone ever recovered BaseCamp successfully with a simple Time Machine recovery after a complete reformatting of their drive? I’d like to go ahead, but not 100% sure that I should trust it. 

(I did go ahead and made a copy of the entire Application Support folder to another large external drive, but it is HUGE and can’t imagine that this should be totally necessary.)

  • Why not make a backup of My Collection from within BaseCamp and restore it later? To make doubly sure you could export My Collection as a GPX and/or a GDB file.

  • Sure. Good thoughts. Have you used any of these 3 backups to completely restore a clean install? Maybe I'm just paranoid, but I picture - at the very least - the dreaded loss of date/time and elevation data so common to version upgrades. 

    My Collection: 8,018 waypoints, 15,316 tracks, 59 Garmin Custom Maps

  • None of the methods are ideal. Backup loses date/time/speed and leaves you with only leg distance, course and position. GPX export seems to choke on large files (reports "out of memory" when I have 16gb!). GDB export preserves the data but loses the directory structure.

    I transferred everything to a new MacBook a couple of years ago but cannot remember if I used Time Machine or Migration Assistant (but it worked).

  • Agree that none of these outcomes are ideal. I have suffered the loss of date/time/speed on several tracks with previous BC upgrades, even without a clean install of macOS.

    Hopefully, the best insurance will be having a copy of my 4.8 database folder with its 147,964 items in its TrackSegments folder along with the files AllData.gdb, AllData.gdb.bak, FolderData.gfi, and FolderData.gfi.bak...

  • The loss of data in tracks is a SEVERE bug that should be a top priority for Garmin but I reported this directly to Garmin months ago and this is the reply I got.  Not very promising
