TidBITS Publishing has released Joe Kissell’s “Take Control of CrashPlan Backups” ebook, which provides help for CrashPlan, CrashPlan+, and CrashPlan PRO.

Kissell helps readers devise a backup strategy for CrashPlan’s capabilities, shows how to back up to multiple destinations and restore files from all of them, explains less-common tasks (such as switching to a new computer and seeding a hard drive locally before moving it to a friend’s house for offsite backup), and walks readers through fine-tuning CrashPlan’s many settings. All three consumer and small-business versions of CrashPlan — the free CrashPlan and the subscription-focused CrashPlan+ and CrashPlan Pro — are discussed, with relevant differences called out. (The book does not cover CrashPlan PROe, the enterprise version.)

The 138-page ebook costs US$10. For more information about the book, including table of contents, author bios, and cover graphic, see: http://shop.oreilly.com/product/9781615424047.do .
