Using whatever tool you have to query MySQL DB: Finds name,filesize,contenthash backup file metadata in DB
select filename,filesize,contenthash from `mdl_files` where (`mimetype` like "application/vnd.moodle.backup" and `filename` not like ".");
Will get something like this:
+----------------------------------------------------------------------+----------+------------------------------------------+
| filename | filesize | contenthash |
+----------------------------------------------------------------------+----------+------------------------------------------+
| backup-moodle2-course-2-backuptest-20121211-0035.mbz | 20287 | 129717ceaec0752f916d8a73c1a96f218fba59ce |
| backup-moodle2-course-38-ipads_1-20130123-1002.mbz | 15453225 | e2c2a07ff231e6f9e0064c44ae4a66a9a27c31c5 |
At the very bottom, one would see the front page backup:
| backup-moodle2-course-1-mdl25-20130901-1507.mbz | 5698873 | 8bb50981e095ef890cfc9e0cbc0b4140ba187138 |
+----------------------------------------------------------------------+----------+------------------------------------------+
Using whatever tool you have to browse files one could verify the file size using the contenthash to locate the directories/contenthash file name.
