I think I’ve made a second rooky mistake in configuring Ubuntu LVM with separate volumes for system (root) and home. I had assumed I could then backup the former via a separate snapshot simply by selecting that volume in one click. Is that possible?
If not, may I suggest a feature to be added to the Source Data page to supports selection of an entire volume rather than selecting the individual directories.
(As I type this I realize this could also be problematic if the swap file is on the root volume. Perhaps a separate swap volume / directory would address that.)
Thanks very much for your patience with my ‘newbee’ question.
Possibly this isn’t your request though. Are you looking for an image backup
or a traditional Duplicati file backup with alternative way to pick mount point?
If you’re into heavy customization of folder selection, image might not fit that.
I’m also not sure if one can do file-oriented restore, but for now I’d guess not.
For your part, maybe you can further detail what you’re trying to accomplish?
Thanks for the response and for links to those documents. Essentially I am aiming for an image from a snapshot of an Ubuntu 26.04 system LVM volume. The destination for the image is a password protected NAS. Is that clearer?
I have read (from the supplied link) that a simple full disk backup is available on Windows only at this stage but that Linux is on your forward roadmap. That sounds good assuming the image can be configured to execute and LVM snapshot and that the image is created from that snapshot.
Thanks very much for the excellent Duplicati software.
I can’t say what the devs have planned. The note says Windows VSS is planned.
LVM support for file backup has been less than VSS, and uses an external script,
which (I think) assumes that your system is set up a certain way. Sounds tricky…
You can check lvm-scripts in Duplicati install folder for how file backup does it.
