- snapshot verify and snapshot restore also list the destination for a snapshot ID that is not in the local index: README, REPOSTRUCTURE, ARCHITECTURE, DATAMODEL and the two commands' help. - prune on a separate machine deletes only unused data and does not remove old snapshots. - The --quiet usage string names everything the flag leaves out. - A warning written as a log record stays on stderr. - config set on a config that does not load refuses three things. - No test is held back by a build tag. - A plain docker build . adds no -dirty. - The backup's order of work records directories. - TODO.md says what parallel downloads would speed up and names restorePlan and restoreSweeper.

Use: "restore <snapshot-id> <target-dir> [paths...]",
|
|
Short: "Restore files from a snapshot",
|
|
Long: `Download and decrypt files from a backup snapshot.
|
|
|
|
This command will restore files from the specified snapshot to the
|
|
target directory.
|
|
If no paths are specified, all files are restored.
|
|
If paths are specified, only matching files/directories are restored.
|
|
A path that matches nothing in the snapshot is named in a warning, and
|
|
the command exits non-zero after restoring the paths that match.
|
|
|
|
The snapshot may be named by its ID or, when restoring on a host with no
|
|
local index, by the remote key that 'snapshot list' prints for a
|
|
remote-only snapshot (an unambiguous leading part is enough).
|
|
|
|
Each file is restored under its original absolute path inside the target
|
|
directory. File owners are restored only when the command runs as root.
|
|
|
|
Requires the age private key, in the VAULTIK_AGE_SECRET_KEY environment
|
|
variable or as age_secret_key in the config file; the environment
|
|
variable wins. The variable may hold the whole age-keygen file, with its
|
|
comments and all of its keys. Read the key from the file rather than
|
|
typing it, so that it does not land in your shell history:
|
|
|
|
export VAULTIK_AGE_SECRET_KEY="$(cat vaultik_backup_private_key.txt)"
|
|
|
|
Also needs permission to read the backup destination store (and to list
|
|
it when given a remote key, or a snapshot ID that is not in the local
|
|
index), and free space in the temporary directory for the decrypted
|
|
blobs.
|
|
|
