Needs more tests. I'm not familiar with all the parallelism, but I think there are parallel processors filling dblock files, and offering them to upload when filled. As these processors run out of work, they drop out, and when all are done a spill collector gathers all the partially filled. Do the parallel uploaders feed off a shared queue that the dblock fillers are feeding? If so, precise control of ordering may be difficult even for start order.
And finish order is less under control because it's subject to variable network delays for different sizes of upload. However the BackendUploader is in charge of pulling from that shared queue and delegates out the actual work of uploading. There is a flush request sent to the BackendUploader which asks it to finish everything in it's queue of work and then quit. The flush request is only sent after all of the processors, including the spill collector, have finished and put their upload requests in the queue.
Before parallel uploading it indeed looks like the dblock and dindex files would be uploaded one by one, and then the dlist file would get uploaded last. Skip to content. Star 7k. New issue. Jump to bottom. Labels bug. Copy link. I have searched open and closed issues for duplicates.
Environment info Duplicati version : 2. Steps to reproduce Add a backup to local folder of a source folder with a Duplicati binary zip file renamed to file.
The latter two are to slow it down and allow you to see when to interrupt it. Export as command-line. Start the exported command line, and press Ctrl-C after the dlist file has completed its uploading.
You will see a dlist and partial dblock. The partial dblock will be deleted at the next backup's start. Update file. Start the exported command line, and let the backup finish. You now have a dblock, dindex, and dlist from second backup, and dlist from interrupted backup. In the GUI, you can attempt to check backup with test command for all files, list-broken-files, and Database Repair.
In general, we list some well-known disasters caused by an abrupt shutdown of a computer that is updating. As you can tell, we can not underestimate the risk of canceling an update while it's installing.
To avoid the risk of your computer being bricked or dead, we have some better ideas for you. Place the system backup image to some external storage devices such as a USB drive, or some cloud storage. When a Windows 10 update is trying to install on your PC without your permission, wait patiently until the update gets over.
Step 2. Guide to your backup destination, choose the system backup file you need. Step 3. Choose the recovery disk. Make sure that the partition style of the source disk and the recovery disk are the same. Step 4. You can customize the disk layout according to your needs. Then click " Proceed " to start system backup recovery. Then, click to select a location to save the backup.
Step 3: Click Options to set up advanced settings. It uses VSS provided by Microsoft by default. Tips: There are still some other settings you can set up.
For example: click general to enable encryption for backups and enable email notification. Click compression to choose the compression level for a backup. Schedule : it allows you to set automatically backup with five modes, namely daily, weekly, monthly, event triggers and USB plug in. Click Advanced to set incremental and differential backup. Scheme : it enables you to manage disk space. It can automatically delete old backups and keep the latest versions of the backup image file.
Noticed that this feature is only available in paid version. What is VSS backup?
