BORG-PLACEHOLDERS(1)

NAME
borg-placeholders - Details regarding placeholders

DESCRIPTION

Repository (or Archive) URLs, --prefix, --glob-archives, --comment and --remote-path values support these placeholders:

    {hostname}
        The (short) hostname of the machine.

    {fqdn}
        The full name of the machine.

    {reverse-fqdn}
        The full name of the machine in reverse domain name notation.

    {now}
        The current local date and time, by default in ISO-8601 format. You can also supply your own format string <https://docs.python.org/3.9/library/datetime.html#strftime-and-strptime-behavior> , e.g. {now:%Y-%m-%d_%H:%M:%S}

    {utcnow}
        The current UTC date and time, by default in ISO-8601 format. You can also supply your own format string <https://docs.python.org/3.9/library/datetime.html#strftime-and-strptime-behavior> , e.g. {utcnow:%Y-%m-%d_%H:%M:%S}

    {user}
        The user name (or UID, if no name is available) of the user running borg.

    {pid}
        The current process ID.

    {borgversion}
        The version of borg, e.g.: 1.0.8rc1

    {borgmajor}
        The version of borg, only the major version, e.g.: 1

    {borgminor}
        The version of borg, only major and minor version, e.g.: 1.0

    {borgpatch}
        The version of borg, only major, minor and patch version, e.g.: 1.0.8

If literal curly braces need to be used, double them for escaping:

            borg create /path/to/repo::{{literal_text}}

Examples:

            borg create /path/to/repo::{hostname}-{user}-{utcnow} ...
            borg create /path/to/repo::{hostname}-{now:%Y-%m-%d_%H:%M:%S} ...
            borg prune --glob-archives '{hostname}-*' ...

NOTE:
        systemd uses a difficult, non-standard syntax for command lines in unit files (refer to the systemd.unit(5) manual page).

        When invoking borg from unit files, pay particular attention to escaping, especially when using the now/utcnow placeholders, since systemd performs its own %-based variable replacement even in quoted text. To avoid interference from systemd, double all percent signs ({hostname}-{now:%Y-%m-%d_%H:%M:%S} becomes {hostname}-{now:%%Y-%%m-%%d_%%H:%%M:%%S}).
