Wildcards for --include-dev

[Proxygen]

While using proxmox-backup-client to backup a standard LXD/LXC host and it's containers, I see the following warnings of content being skipped:

skipping mount point: "snap/core/14447"
skipping mount point: "snap/core20/1778"
skipping mount point: "snap/lxd/24323"
skipping mount point: "snap/snapd/17950"

which is to be expected, since it skips mountpoints by default.

I could manually include in the backup script arguments such as `--include-dev /snap/core20/current`, but this will become a pain to manage as you add and remove snaps. It seems that I cannot use wilcards to designate mountpoints for `--include-dev` -- it only takes full paths.

Long story short, is there any way I can work around this limitation for `--include-dev` which will not change as snaps get added/removed?

TIA

Hi,
maybe you can use --all-file-systems and --exclude instead? With exclusion, globs/wildcards are supported, see here. Exclusion can also be done via .pxarexclude files containing the relevant globs. Note that entries not starting with / will also match recursively in each sub-directory!

Thanks Fiona. "entries not starting with / will also match recursively in each sub-directory" applies to --exclude also or only .pxarexclude?

Both. Also, please note that the arguments to --exclude with a leading slash will match relative to the archive's root, not the full filesystem path on the host.

Unless the archive's root is set to the root of the host, right?

I did use

--all-file-systems

and it still skipped

/var/snap/snapname/snapversion/* /var/snap/snapname/current/*

.

What gives?

Can you share the output of proxmox-backup-client version, the command you are using for the backup and the output of the command (feel free to shorten it if there is a lot of similar/repeated output).

 

[Proxygen]

3.0.2, using --all-file-systems --exclude /proc --exclude /dev --exclude /run --exclude /sys

--all-file-systems --exclude /proc --exclude /dev --exclude /run --exclude /sys
