It can do some of those things in some modes of operation, and others in other modes of operation, but not all of them at once.Use rsync to Sync a Node Project to Dropbox and Ignore the node modules Folder The short answer, I think, is that there is no way to meet all of your criteria exactly, and I don't think that even bvckup2 does. That also violates your stated requirement of operating directly over SMB. Such a backup application relies on the filesystem to provide efficient snapshots, and a means of sending the snapshot delta directly to the remote system. The bvckup2 docs suggest a third option, which is to use filesystem-specific journals for the backup, and for that option, the closest thing on Linux is going to be or something like it. A program that connected directly using a built-in SMB client might be able to do better.) (As far as I know, SMB3 does have an efficient file-copy request in the protocol, to offload that to remote servers, but it's not exposed by the Linux kernel. That seems less reliable than I would like, but more importantly, if you're backing up over SMB, Linux does not have an API to efficiently create a second copy of the file on the backup destination. The documentation also suggests alternate strategies, like caching information about the remote file's block hashes.

It can avoid the problem of reading the entire file if rsync is installed on the remote system, but that violates your requirement of backing up over SMB and not requiring specific software on the server. The bvckup2 documentation on delta copies discusses those challenges and trade-offs ( ).
#BVCKUP 2 REDDIT FULL#
Because it stores chunks of files by hash, it can determine what portions of large files have changed without reading them from the remote system, so it can avoid the full copies, but it isn't storing raw files on the destination. It is technically possible to do backups to SMB, and not to have special software on the remote end, but copying only changed portions of the file in such a setup isn't possible, because the backup client has to read the entire file from over CIFS to determine what portions have changed, and at that point you've copied the entire file in at least one direction.īorgbackup, on the other hand, can meet all of your criteria except backing up files raw. Rsync based backup systems like rsnapshot will do most of what you're doing, but there are a few of your requirements that are. But Linux is used heavily on servers so I would expect a simple app with these features to be available. At this point I can compromise this.Īctually when looking for Backup software for Windows, I was unable to find such app except Bvckup2.
Copying over only changed parts of files (what Bvckup2 calls "Delta copy", useful for VM VHDs).
#BVCKUP 2 REDDIT INSTALL#
Not having to install server software, I want files to be transferred via SMB (most enterprise backup software for Linux require that, this is overkill for such a simple backup setup) Deleting files immediately defeats the purpose of a backup but not deleting them makes a mess on the backup and also takes up unnecessary space. Syncing deletions but keeping deleted files for x days in an "Archive" folder (on remote).
#BVCKUP 2 REDDIT PC#
Also I can browse my PC files from another device while the PC is off. This makes the recovery really easy and fast. Backing up files raw (aka just copying files, no compression or encryption).
The features I'm looking for that Bvckup2 has: When I had Windows, I used to use Bvckup2 but I'm yet to find an app like this for Linux. I have a "NAS" on my network (aka a Raspberry PI with an HDD running an SMB server) and I have setup my devices (Phone, PC, other PIs) to automatically backup in there.
