![]() ![]() I wrote the format, and I would never modify them myself because I know that later when I go to restore my files it will simply not work because this file was modified. C:\dog.jpg" that means that Backblaze discovered the file C:\dog.jpg was deleted from your local drive at year 2022, month 02, day 03, hour 04, minutes 05, and seconds 06. Oh, column 3 in that slide is the date time that that event occurred. Find the little "gear" icon and maybe change the "Playback Speed" to be 1.5x speed to get through it in 30 minutes. ![]() It was a video orientation for new employees. You can watch a 40 minute video tutorial I give on how to read these files in this YouTube video: You can start at timestamp offset 18 minutes, this was an internal talk at Backblaze not meant for external consumption. It also added iOS and Android apps to make getting individual files back a snap. It also offers a hefty discount to Safe Prime. Backblaze also tried to make the restore process as painless as possible, first with free web restores (allowing you to download and access your data from anywhere) and then with our DVD (now flash key) and HDD USB restores. The former charges 99 per request, regardless of size. Ok, so the filename that the "+" or "-" applies to is at the far far far right of each line. In terms of courier recovery prices, Carbonite is significantly cheaper than Backblaze. Finally, if you see an "x" in column 1 then the file has been deleted from your laptop for more than 30 days and it is no longer in your backup on the server side either. If column 1 is a "-" (minus) sign then you deleted the file locally from your laptop. In column 1 you see will be a "+" if the file was added to the backup. If you look at the "column labels" in that slide Column 1 is the most important column. All lines start with a "5", that is the line version number and you can ignore it. Ok, here is the basics of the file format. The file should look like this screenshot: That is a slide that is meant to be printed on an 8.5"x11" piece of paper in landscape mode and still be readable. You can open the files in WordPad on Windows, and TextEdit on the Mac, and make the window really really wide and turn off all line wrapping. So if something occurred on let's say March 27th it would either be in bz_done_20220325_0.dat or bz_done_20220329_0.dat and most definitely not in the final file of bz_done_20220401_0.dat which I hope makes sense. The "date" in all three of those filenames is in the format YYYYMMDD (Year, Month, Day). Ok, so the file names have dates in the file names corresponding to around what day the event occurred, so they might look like this: So please make a copy of that folder somewhere else on your disk and then look at the copy. Just don't do it, you will corrupt your backup. Ok, so I'm begging you, DO NOT MODIFY EVEN ONE CHARACTER in those files. On Macintosh /Library/Backblaze.bzpkg/bzdata/bzbackup/bzdatacenter/ On Windows: C:\ProgramData\Backblaze\bzdata\bzbackup\bzdatacenter\ How can I determine which files were deleted between backups or between a time frame?īackblaze records all of the things that occurred in pretty easily understood files called "bz_done" files, they are what was "done" to the backup. Disclaimer: I work at Backblaze and wrote the code that records what files you deleted. ![]()
