What is a random sample of dlist?
Verifies integrity of a backup. A random sample of dlist, dindex, dblock files is downloaded, decrypted and the content is checked against recorded size values and data hashes. <samples> specifies the number of samples to be tested. If "all" is specified, all files in the backup will be tested. This is a rolling check, i.e. when executed another time different samples are verified than in the first run. A sample consists of 1 dlist, 1 dindex, 1 dblock.
What does "backup" mean in Dlist?
Marks old data deleted and removes outdated dlist files. A backup is deleted when it is older than <keep-time> or when there are more newer versions than <keep-versions> . Data is considered old, when it is not required from any existing backup anymore. Usage:

You can also start certain operations for a specific backup job here.
Why do Duplicati backups use local databases?
Duplicati makes use of a local database for each backup job that contains information about what is stored at the backend. Main reasons for storing this information locally are performance and reduction of bandwidth usage. Without this database, Duplicati would need to download a fair amount of data from the backend for any operation.
What encryption does Duplicati use?

How does Duplicati work?
Duplicati analyzes the content of files and stores data blocks. Due to that, Duplicati will find duplicate files and similar content and store this only once in the backup. As Duplicati analyzes the content of files it can handle situations very well if files and folders are moved or renamed. As the content does not change, the next backup will be tiny.
What is a dualcati?
Duplicati is designed to handle various kinds of issues: Network hiccups, interrupted backups, unavailable or corrupt storage systems.

And even if remote files get corrupted, Duplicati can try to repair them if local data is still present or restore as much as possible.
Does Duplicati work with storage?

Does Duplicati support compression?
All backup data is compressed before it is encrypted and uploaded. Duplicati supports Zip/Deflate or 7z/LZMA2 compression. For performance reasons, Duplicati detects files that are compressed already and adds those as they are to the Zip or 7z archives. For example, media files such as mp3, jpeg or mkv files contain very well compressed data already.
Does Duplicati backup data?
Duplicati performs a full backup initially. Afterwards, Duplicati updates the initial backup by adding the changed data only. That means, if only tiny parts of a huge file have changed, only those tiny parts are added to the backup. This saves time and space and the backup size usually grows slowly.

Is Duplicati client stable?
