我想使用borg备份和systemd计时器来进行备份。我正在使用 borg 备份网站上的脚本，稍作调整。你可以看看原图这里和我的脚本如下：
#!/bin/sh
# Setting this, so the repo does not need to be given on the commandline:
export [email protected]:/path/to/repo
# See the section "Passphrase notes" for more infos.
export BORG_PASSPHRASE=SecretPassphrase
# some helpers and error handling:
info() { printf "\n%s %s\n\n" "$( date )" "$*" >&2; }
trap 'echo $( date ) Backup interrupted >&2; exit 2' INT TERM
info "Starting backup"
# Backup the most important directories into an archive named after
# the machine this script is currently running on:
borg create \
--remote-path=/usr/local/bin/borg \
--verbose \
--filter AME \
--list \
--stats \
--show-rc \
--compression lz4 \
--exclude-caches \
\
::'{hostname}-{now}' \
~/.ssh \
~/db/dump_* \
backup_exit=$?
info "Pruning repository"
# Use the `prune` subcommand to maintain 7 daily, 4 weekly and 6 monthly
# archives of THIS machine. The '{hostname}-' prefix is very important to
# limit prune's operation to this machine's archives and not apply to
# other machines' archives also:
borg prune \
--remote-path=/usr/local/bin/borg \
--list \
--prefix '{hostname}-' \
--show-rc \
--keep-daily 7 \
--keep-weekly 4 \
--keep-monthly 6 \
prune_exit=$?
# use highest exit code as global exit code
global_exit=$(( backup_exit > prune_exit ? backup_exit : prune_exit ))
if [ ${global_exit} -eq 0 ]; then
info "Backup and Prune finished successfully"
elif [ ${global_exit} -eq 1 ]; then
info "Backup and/or Prune finished with warnings"
else
info "Backup and/or Prune finished with errors"
fi
exit ${global_exit}
ATM 我只是想设置一项服务，没有计时器。
我n.service在 中创建了（工作名称）/etc/systemd/system，内容如下：
[Unit]
Description=Example Service
[Service]
Type=simple
User=callmebob
Group=callmebob
Environment="[email protected]:/path/to/repo"
Environment="BORG_PASSPHRASE=SecretPassphrase"
ExecStart=/bin/sh /home/callmebob/backup.sh
[Install]
WantedBy=multi-user.targetshell
现在从控制台：
sudo systemctl daemon-reload
sudo systemctl start n
sudo systemctl status n
服务似乎运行正常，但它永远无法读取环境变量：
May 18 05:45:31 mydomain systemd[1]: Started Example Service.
May 18 05:45:31 mydomain sh[213874]: Wed 18 May 05:45:31 UTC 2022 Starting backup
May 18 05:45:38 mydomain sh[213903]: passphrase supplied in BORG_PASSPHRASE, by BORG_PASSCOMMAND or via BORG_PASSPHRASE_FD is incorrect.
May 18 05:45:38 mydomain sh[213903]: terminating with error status, rc 2
我尝试使用EnvironmentFile，在其中放置键/值对，没有引号等，但也不起作用。使用PassEnvironment也没有任何作用。我也尝试了不同的服务类型，但没有成功。
知道我在这里缺少什么吗？
