![]() The four I mentioned above are the ones I recommend because they fall into a category of backup software that offers the best of both worlds, “Full” and “Incremental” backups.Įach time you run the backup, they scan your files and only send the new or changed files to your backup destination. How does backup software like the ones I mentioned above determine which files have changed? Basically the exact same method. How does “sync” software determine when/which files have changed? They periodically scan the directory for changes to the file’s metadata (file size, last changed date, etc.) and then check the hash of the file against the last sync’d copy. I would point to Duplicati, Restic, Borg, and Kopia as good open source options to consider. Let’s me set up multiple different “profiles” that I choose to run when I want and depending on the situation.Īctually, a lot of the backup tools mentioned so far work this way. I’m on Windows, and as someone else mentioned, I also used FreeFileSync at one point, but now only use SyncBackFree. Restoring from a full backup would be a nightmare if you don’t use starring or colour codes properly to easily see what you’ve deleted in the past. But for me I’m ruthless on culling photos - if I delete, they are gone. Many people use full Backup mode…they like the fact that nothing gets deleted. I do use one external portable drive and while on the road will edit photos - for this I use Mirror since I want the destination location (the portable drive) to copy changes over to the source drive (my hard drive). If I edit in Capture One, only the catalogue and some other text files are copied when I Synchronize. ![]() If I import them in darktable and make some edits, then run Synchronize again, only the xmp files are copied since those are the only files new or changed. So when I load new image files on source, synchronize copies them to destination. Mirror: All new, changed and deleted files on either source or destination are changed on the other drive. Deleted files on source get deleted on destination, but any changes on destination do not get changed on source. Synchronize: All new and changed files from source are copied over to destination. Deleted files on source do not get deleted on destination. Backup software I’ve used has generally had 3 different modes:īackup: All new and changed files from source are copied over to destination.
