Hi everyone,
I’ve set up a working Restic environment on my Synology NAS and wanted to ask if anyone has experience making FUSE-mounted Restic repositories searchable (<>? indexable) by DSM’s File Station or the built-in Synology indexing service.
Here’s my setup:
-
Synology NAS (SM 7.2.2-72806 Update 2) DS923+
-
restic/rest-server:latestrunning in Docker (for rest) -
Backups from several clients (including my notebook) to that rest-server repository
-
Repository mounted locally on the NAS for browsing and validation (using restic binary installed manually)
The rest-server container is configured like this (simplified):
{
"image": "restic/rest-server:latest",
"port_bindings": [{ "container_port": 8000, "host_port": 9001, "type": "tcp" }],
"volume_bindings": [
{ "host_volume_file": "/NAS2_Share/restic", "mount_point": "/data/volume_backup", "type": "rw" }
]
}
And I use a local mount script on DSM (run manually or via task scheduler):
#!/bin/bash
REPO_PATH="/volume2/NAS2_Share/restic/Aorus_backup"
MOUNT_PATH="/volume2/NAS2_Share/restic/mount"
RESTIC_BIN="/usr/local/bin/restic"
case "$1" in
start)
fusermount -uz "$MOUNT_PATH" 2>/dev/null || umount -lf "$MOUNT_PATH" 2>/dev/null
rm -rf "$MOUNT_PATH"; mkdir -p "$MOUNT_PATH"
"$RESTIC_BIN" -r "$REPO_PATH" mount "$MOUNT_PATH"
;;
stop)
fusermount -uz "$MOUNT_PATH" 2>/dev/null || umount -lf "$MOUNT_PATH" 2>/dev/null
rm -rf "$MOUNT_PATH"; mkdir -p "$MOUNT_PATH"
;;
esac
This setup works fine — I can browse snapshots locally on the NAS in the File Station (not searching though), and Restic mount behaves as expected when opening files (PDF viewer for example)
However, DSM’s File Station cannot search inside the FUSE-mounted folder (/volume2/NAS2_Share/restic/mount).
Interestingly, if I mount the same repository remotely from WSL on Windows, the mounted filesystem is searchable there (wsl mount) Windows File Explorer can search within it like any other folder (like *.pdf)
So my questions are:
-
Is this a known limitation with Synology’s FUSE implementation or DSM’s indexing service or rather some permission issue (would be strange though, as I can still open files..)
-
Is there any known workaround (mount options, permissions, or service restarts) to make FUSE-mounted Restic repositories visible to Synology’s search system?
-
If not, is the only practical way to search through snapshots via the Restic CLI (
restic ls, etc.) or via a different mount tool (e.g., using rclone mount or webdav)? Probably a own applet could be written for synology I guess.
Thanks a lot for any hints → the setup otherwise works great, but it would be very convenient to make the mounted repository searchable directly in DSM (I know that for heavy use, restore is recommended, but that would eat NAS space if I just need to find something in particular.)
Note: I tried using `/volume1/homes/{username}/.local/bin/restic `
and explicitly `RESTIC_CACHE_DIR=/volume1/homes/{username}/.cache/restic` as well to mount it, but concerning searchability it did not do any difference (so root vs user in File Station, seems not to be the issue)
