How to compare backups
Comparing backups is useful in the following scenarios:
- You have 2 backups of your site and you’r enot sure which one you want to restore
- You want to compare a backup to your current site
- Your site has been hacked and you want to know what has been changed
On your Linux web server command line, type:
diff -r -x cache www.backup1 www.backup2
In this command
www.backup2 represent the 2 file structures you want to compare.
-x cache allows you to ignore the cache folder, since it is almost guaranteed the caches will be different.
An even better way, may be to just ignore the *.page files in the cache, like this:
diff -r -x "*.page" www.backup1 www.backup2
The easiest way is to export the database to a file backup and then compare the files.
