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/3.10/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/3.10/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}).
