Basecamp Alldata.gdb and Alldata.bak files Overwritten, database gone?

When launching BaseCamp v4.7.5, an error stating something about a list file popped up and I clicked "Attempt to Repair." I didn't write down exactly what the error said, and I cannot reproduce it.

BaseCamp booted up normally, however my entire database is gone. No waypoints, tracks, or routes from 8+ years of adventuring are present. 

The AppData\roaming\Garmin\BaseCamp\Database\4.7 directory shows AllData.gdb and AllData.bak as 2KB files.

My assumption is that BaseCamp overwrote the existing database files and simply deleted the old ones.

Is there any way to get the previous database back? I do not have a manual backup besides the little data on my GPS because I blindly trusted that Garmin would have redundancy for this and would not just overwrite all previous data without saving the corrupted file separately. 

  • Any data file should be backed up, regardless of whether it's BaseCamp, Word, Excel etc ... if you have some sort of routine back up set you may find it there. However BaseCamp also can work with numerous  AllData.gdb files, it may simply be that you've set it to look at the wrong one. Do a search for AllData.gdb files and see if you have any others. Point BaseCamp at any you find and see if your data is there.
