How do you maintain and backup your ebook library? - Page 8

Robocopy is another alternative to SyncToy, and comes built in as a standard part of Windows Vista and Windows 7. However, it's command-line only, while SyncToy has a GUI.

Thank you Harry.

My Calibre has crashed and now all my settings are gone.

If I want to open my "old" library, the following message appears:
calibre, version 0.9.38
Beschädigte Datenbank: Die Bibliothek Datenbank bei D:\Calibre Bibliothek scheint beschädigt zu sein. Möchten Sie, dass Calibre versucht diese automatisch wiederherzustellen? Die Wiederherstellung könnte nicht komplett erfolgreich sein.

Simply restore your backup. That's what this entire lengthy thread has been about. That's why you make backups.

You might get some help on that over in the Calibre forum.

Your library of books is still there correct? Are you running Windows. If so did you make a backup of your 'AppData' folder. Your Calibre settings should be in there.

idraw22 · 07-15-2013, 10:53 PM

Pretty much the same on my end, except I don't add my books to Calibre unless they need work done, (converting, metadata, etc) then I copy to two sticks, one for the whole library, and one just for Calibre. I add books to ereaders if necessary too.

Same here -- I've been just dragging and dropping the folder onto a storage card few times a year.

For anyone who wants to sync between two computers, regardless if they're on the same LAN/subnet at all times, here's a freebie that works wonders.

Like others here, I have been backing up books and photos for a long time. Unlike most, I still have a couple of 8" backups. Been a long time since I could read them!

I just copy everything onto a DVD. The blanks are cheap and they've proven to be quite reliable. Being of a somewhat paranoid nature and distrustful of anything digital, I usually create par2 (parity error correction) files as well. Usually about 10%. For the files I really want to keep, mostly photos (I have negatives that go back more than 50 years now) I also use DVDDisaster to create ecc files. The par2 files will fix files if there is an error reading the file. The ecc files help if there is an error in the directory area of the disc. I don't expect any digital media to last as long as my oldest negatives.

I usually send a duplicate of the disc to my brother as a second backup. Blanks are cheap, most computers with optical drives are DVD writers now and it doesn't take long to do. Cheap insurance against loss.

My PCs always have 2 identical sized drives in them and I periodically clone Drive C (the only one used) to Drive D. If anything ever goes wrong, it's just a quick reboot to the 2nd drive and I'm back up and running until I figure out what happened to the C Drive. I used Acronis TrueImage and set it clone when I go to sleep, but even for near full 1TB drives, it only takes a couple of hours to clone a drive. I love that program.

I don't do the cloning as often as I should though, it might be 3 months between doing it again, so recently I started using a file sync program for just a few directories like documents, Calibre library, and my photos, and I sync those nightly across my LAN. After trying out quite a few programs, the one I like the best is FreeFileSync. Not only is it free, but it's easy to use, you can have it constantly monitor certain directories and sync them constantly, or run it when you want, or what I do is have it set as a Windows Task to do nightly. It can sync just from one PC to others (my main use), or sync both ways between 2 PCs. Here's 2 sites that give good explanations how to use the program:
