In terms of back up speed, would splitting a VirtualBox virtual disk into smaller multiple files decrease the time it takes to rsync?
by wh33t from LinuxQuestions.org on (#4Z9H6)
Currently I have a 1.8TB Nextcloud Vbox. It has a single virtualdisk that is set to expand as needed up to 1.8TB, currently it is around 550GB. Using Rsync, it takes about 1.5Hours to copy from the 2TB HDD on it's on, to an exact mirror drive in the same system. The transfer averages about 100MB/s.
Other than replacing both HDDs with SSDs (which I do intend to do as funds permit) I was curious if splitting the virtualdisk into multiple smaller files would make rsync go faster. The theory being that if only one or two of the virtual disk chunks change, then only those will need to be transferred due to the magic of rsync.
Is this a solid theory or completely wrong?
Also, while I've got you here, can I modify my existing Vbox to use multiple virtualdisk files?
Thanks so much for reading!
Edit: Nevermind. I seem to be confused. I thought virtualbox could split a virtualdisk into smaller pieces. Perhaps I'm thinking of VMware.
Edit2: Apparently Virtualbox can do this, but you can't do it with the GUI or with Virtualboxes own virtualdisk format. LINK
