Incomplete Backups
- Ed Bobak
Has it been a while since the computer has backed up to 100% in crashplanner? Here is a command we can run on both Mac and Windows to try and find out what files might be holding us back from backing up to 100%.
Mac Terminal:
sudo grep -e '^W' /Library/Logs/CrashPlan/backup_files.log.0 | tail -10Output on Mac:
W 02/10/25 12:58PM 43 - /Users/ebobak/Library/Group Containers/group.com.apple.CoreSpeech/Caches/onDeviceCompilationCaches/speakerRecognition/24D5055b-915b2b7b58cda908d393076c1774553c56bf6550_15.1033.1-int8_conformer_matrix_split-15.1033.1-en-US.bnnsir
W 02/10/25 01:47PM 43 - /Users/ebobak/Library/Containers/com.apple.Safari/Data/Library/WebKit/WebsiteDataStore/c38ae4b9-bf8f-4a8c-bb9e-fee44883203e/AlternativeServices/AlternativeService.sqlite-wal
Windows Power Shell:
Select-String -Path "C:\ProgramData\CrashPlan\Log\backup_files.log.0" -Pattern '^W' | Select-Object -Last 10Output on Windows:
Now looking at this data in the first line we see that ~/Library/Group Containers is being called out. We can ignore that folder in this path by going into the crashplan application, logging in with your umich email address, and clicking on Managed Files in the top right.
Click into the folder path to the location of which folder you’d like to exclude and test the next backup. Showing the ~/Library folder here:
Click Save in the bottom right and ok to this data being removed from the archive. On the second line of the output we see it is trying to backup something with Safari. Let's quit Safari for a few minutes here to see if it now backs up. Back to the Crashplan and the home page, click backup now.
This might take a bit and get closer to 100% or complete. If it does not hit 100%, grab some new output from the logs with the commands above to repeat removing another folder or closing another application like Thunderbird.
Reach out on slack should you have questions about removing different file paths.
