When we wrote about the Google-data backup application CloudPull 2.0, the most obvious problem was its performance when bringing in large quantities of email from Gmail (see “Back Up Your Google Data with CloudPull,” 6 March 2012). John Brayton of Golden Hill Software took note of this, and improved the performance significantly in CloudPull 2.0.2 by addressing inefficiencies in how CloudPull interacted with Gmail via IMAP. But that has remained his focus for the just-released CloudPull 2.1, where he has enabled CloudPull to use four simultaneous connections for far faster performance yet. That in turn tends to set off Gmail’s throttling for clients that use excessive bandwidth, so CloudPull 2.1 also restricts itself to 5000 messages per backup cycle to avoid being throttled. As a result, initial backups can still take a while, but subsequent backups can be over 10 times faster than 2.0.2. Equally important from the perceptual standpoint, CloudPull 2.1 now has an Activity window that tells you what the app is doing and provides progress bars. Other changes include a Check for Updates menu item, improved usability in the Google Accounts preference pane, a text-label switch from Google Docs to Google Drive, pagination of lists with over 1000 items, and retry and backoff logic to make individual backup cycles more resilient to connectivity problems and errors from Google. CloudPull 2.1 requires Mac OS X 10.7 Lion; version 1.5.7 remains available for those running 10.6 Snow Leopard. ($24.99 new, free update, 7.6 MB, release notes)
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
