check / check (push) Failing after 15m58s
Print a failed command's error once on stderr (closes #433)
A command that failed after startup wrote the error twice on stderr:
as an ERROR log record and as the final ERROR: line. The failure
handlers now log the failure at info level, so the record appears only
under --verbose or --debug, next to the records that led up to it.

A failed blob upload is logged at info level for the same reason. A
restore that stops on a file it cannot restore no longer logs that
file's error, which the final line carries; under --skip-errors it is
still logged.

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).
Requires the age private key in the VAULTIK_AGE_SECRET_KEY environment
variable. The variable may hold the whole age-keygen file (comments and
all of its identities are accepted); read it from the file rather than
typing the key, so it does not land in your shell history:
export VAULTIK_AGE_SECRET_KEY="$(cat vaultik_backup_private_key.txt)"
Examples:
# Restore entire snapshot
vaultik snapshot restore myhost_docs_2025-01-01T12:00:00Z /restore
# Restore specific file
vaultik snapshot restore myhost_docs_2025-01-01T12:00:00Z /restore \

vaultik snapshot restore myhost_docs_2025-01-01T12:00:00Z /restore \
