remembers what's there and the incrementally updates this snapshot as it works its way through the backup. ![]() It defaults to maintaining a local snapshot of the destination, instead of re-scanning it on every run. Not a rocket science by any means, but this can speed things up by a factor of 10 when scanning slower NASes over laggy networks.Ĥ. It uses parallel disk scanning, when building the file lists for source/destination locations. It has a higher bulk copying speed than newer robocopy versions and other specialized 3rd party programs that I have tested.ģ. ![]() This eliminates unnecessary idling when copying and helps keeping the copying pipeline busy at all times. It uses fully asynchronous I/O with adaptive buffering, meaning that the app never waits for a read/write request to complete before issuing the next one. With delta copying a day worth of changes takes under an hour to propagate.Ģ. I run a backup that includes 256 GB TrueCrypt container and straight copying to an external USB3 drive takes about 4 hours. This speeds things up, in many cases dramatically. It uses delta copying to update file modified between the backup runs, so that it copied only modified blocks of files. It merely copies things from A to B, as is, and it is exceedingly good at it.ġ. It is not a all-in-one backup tool, it doesn't compress things, it doesn't FTP or encrypt files nor does it have a restore function. It's not a system backup, it doesn't create a system image that can be used to restore a bootable system after a failure. If you are currently doing your backups by copying files from your primary machine to an external drive or a NAS, the app will help you do it better, faster and in altogether more pleasant format. Kudos to Aram for not only managing to trigger this issue, but also for noticing and reporting it.ĭownload: Bvckup 2 Release 80.8 | 2.4 MB (Free trial, $19.It's a simple data backup software that is meant for mirroring directories. So the rename went through, but the update didn't, the file ended up looking like is was still in sync with the original. The problem was file's current timestamp was recorded in the snapshot after the rename and then again after the update.It has to do with handling of files that get renamed _and_ updated between the backup runs when the backup is aborted between these two actions. Fixed an issue with destination snapshot management.This is a workaround for QNAP devices that will report Archive attributes set on files, but refuse to clear them. Revised file attribute handling logic a bit - starting with this release, if the program sees a file system volume that supports the Archive attribute ONLY, then it will act as if this attribute is NOT supported either.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.
