Generally, programs like Calendar know best when it comes to identifying which files should be backed up and which ones shouldn't. To avoid unnecessary backups, the Calendar application attaches metadata to the Calendar cache file that says, “Don't back this up.” The Code42 app is smart enough to note the request and ignore the file.Īny program on Mac OS can tag any file with the “Don't back this up” metadata. Basically, it's a complete waste of time to back up.
And if you delete the cache, a new cache file is started automatically. However, it doesn't contain your actual calendar entries those are maintained in other files. The Calendar cache file is a convenience to make the Calendar entries load more quickly, and it changes every time you add, remove, or edit a calendar entry.
