![]() ![]() Snapshot migration: all or selected snapshots can be migrated from one storage to anotherĭuplicacy also comes with an elegantly designed GUI that features one-page configuration to allow you to quickly set backup schedules and retention policies. ![]() Concurrent access: multiple clients can back up to the same storage at the same time.Deletion: every backup can be deleted independently without affecting others.Encryption: encrypt not only file contents but also file paths, sizes, times, etc.Deduplication: identical files must be stored as one copy (file-level deduplication), and identical parts from different files must be stored as one copy (block-level deduplication).Full snapshot : although each backup is incremental, it must behave like a full snapshot for easy restore and deletion.Incremental backup: only back up what has been changed.Duplicacy is the only cloud-backup tool that offers all the following 7 essential features: This is all pretty opinionated, so feel free to prove me wrong.Duplicacy is a new generation cloud-backup tool supporting 5 major cloud-storage providers (Amazon S3, Google Cloud Storage, Microsoft Azure, Dropbox, and Backblaze), as well as local disks and SFTP servers (such as Mac/Linux computers or NAS boxes). So I'm sticking with chunking for the time being. There is also the corner case of metadata in media files such as EXIF, which if modified would cause the whole file contents to be stored again. gdb format which is based on Sqlite3 or PowerWorld's. ![]() There are still plenty of file formats that are uncompressed text, even newer ones such as JSON/YAML/TOML and a number of uncompressed binary file formats such as MessagePack, though most tend to be some sort of database such as the Geodatabase. The gotcha to this is it's an 80% solution. More recently, this format also includes Matlab's. MS office documents structured as a hierarchy of zipped.This suprisingly (to me) also includes raster image editor file formats such as 's pdn, which wraps everything in a gzip stream. Audio/Image/Video files with (usually) lossy compression.For most users this wouldn't impact disk space usage much as the bulk of files already have compression built in, and the trend seems to be increasingly to adopt compression in new file formats. This would probably result in significant simplification, particularly for copying between repos. I love Linux, but I'm a practicing engineer, and the reality is that engineering software is a market where traditional Windows desktop software still rules.Īnother thought I've been having for some time is if I could have gotten away with file level deduplication like Boar (or Git IIRC) does and drop compression. Is truly cross-platform with minimal POSIX dependencies.Doesn't keep state in the working directory so that projects can live in a Dropbox/OneDrive/iCloud folder without corrupting the repo. ![]()
