It also happens to be the milestone that we crossed (on February 5th, 2020 at 14:47 UTC) for files restored from our <a href=\"https:\/\/www.backblaze.com\/business-computer-backup.html\">Computer Backup<\/a> service! Back in <a href=\"\/blog\/20-billion-files-restored\/\" target=\"_blank\" rel=\"noopener noreferrer\">2016, Backblaze hit 20 Billion<\/a> files restored for our customers. It took us almost 9 years to get to that number, and only another 4 years to more than double it (and that\u2019s not even including all the Backblaze <a href=\"https:\/\/www.backblaze.com\/docs\/cloud-storage-about-backblaze-b2-cloud-storage\">B2 Cloud Storage<\/a> files that get accessed and downloaded every day).<\/p>\n<p>50 Billion is a giant number, but it\u2019s not <em>just<\/em> a number to us. It\u2019s baby pictures, first step videos, PhD theses, long lost tax forms from years past, powerpoint presentations, digitized family albums, art projects, documents and writing, manuscripts, book outlines, and all manner of memories. We love that we\u2019ve built a sustainable business around restoring people\u2019s files which they may have thought were lost forever.<\/p>\n<p>The last time we wrote about a restore milestone we went in and took a look at a typical month in the life of our restore system.
