1 Gbps wire link.įor local copies it should also have noticeable effect, but again, the faster the drives the more pronounced the effect should be. The effects of parallel copying are most pronounced when copying to or from a network shared, and especially when going over a fast connection, e.g. ! Make sure to exit the app before making any INI changes or your changes will be ignored and overwritten by the app. The default is 0, which is the 16-4-1 auto behavior described above. It is possible to override the thread count by changing the following option in job's settings.ini: It will log the exact thread count in Processing section of the log:Ģ016.10.07 15:09:54.872 (UTC+1) 2 0 Running the backup. * 1 copy at a time if backing up in confines of one drive * 4 copies if copying between two local drives and * 16 file copies in parallel if copying to or from a network share We now have a reasonably stable build that supports parallel copying and you are welcome to play with if you'd like: * This is similar to the robocopy /mt option if you are familiar with the tool. For larger files the opening/closing time is dwarfed by the copying time, but for smaller files they are comparable, so if we can task the OS with opening/closing several files in parallel, then we speed things up. When a file is copied, there's a fixed time cost of opening and closing it and then there's a cost of actual copying that is proportional to the file size. ĭownload: Bvckup 2 Release 79.03 | 2.0 MB (Free trial, $19.As you might've heard Bvckup 2 is getting support for copying several files in parallel during a backup. In fact, you can now yank an USB drive from its port in the middle of a write and Bvckup 2 will automatically correct the file corruption that this may cause, while preserving as much of existing data as possible.Īdditionally, the ultra copier looks at the exact drive type (HDD, SDD, NVMe, etc.), USB connection details and a network protocol version to adapt its IO profile for the setup. Copying is now resumable after cancellations and IO errors.To the point that it can now shovel data between two NVMe drives with virtually no impact on the speed over regular bulk copy. Faster in bulk copying and faster in processing of smaller files.The previous version is still perfectly fine, but it is now several years old and we've learned a thing a two during that time. The central piece of code that shuffles data from a file to its backup copy was completely redone. This is a big change, which was long due. Templating of new backup jobs is now simpler.Better handling of the OneDrive folder and offline files.Ctrl-A now selects all text in edit boxes.New progress bar for bulk and delta copying.Delta copying thresholds are now 16 MB and 64 MB (see below).Flushing is now Off by default for removable devices.Resolved an issue with "Another instance is running" popup.Resolved two issues with handling of file symlinks.Resolved an issue with losing UI config file on machine reboots.Support for disabling tray alerts for missed backups.Support for retrying backup steps on transient failures.Brand new copying module dubbed the "ultra copier".Optimized throughout for no run-time bloat.Backup of locked files with shadow copying.Real-time, scheduled and manual backups.Ideal for making local backups, backups going to external and removable drives as well as to NAS devices. It does however include a comprehensive list of supporting features including periodic and real-time backup scheduling, removable device tracking and shadow copying support. The software replicates files from one location to another in their original format and purposefully does not include options for compressing or encrypting them. Bvckup 2 is a mirroring data backup software notable for its use of delta copying, speed of operation, small resource footprint and a "beautifully functional" user interface.
