#  Backup Manager Configuration File
#
#  * This configuration file is divided into sections.
#    The 'global' section is mandatory, every keys defined in 
#    this section are inherited in the other sections.
#  * There is one section per "backup method", you have to 
#    fill the section of the chosen method.

# $BM_ARCHIVE_PREFIX-$BM_PIPE_NAME.$DATE.$BM_PIPE_FILETYPE
# If you specified a BM_PIPE_COMPRESS option, the resulting filename 
# will change as expected (eg, .gz if "gzip").

Вопрос при таком значении BM_REPOSITORY_ROOT будет ли отрабатывать параметр BM_ARCHIVE_TTL? Хотелось бы упорядочивать архивы каждый в каталог с текущей датой. Как это сделать правильно?

★★★★★

Ладно, попробую убрать BM_ARCHIVE_TTL и вместо этого по крону выполнять

find /backup/* -mtime +10 -exec rm {} \;

Задача удалять бекапы старше 10 дней из репозитория.

find /backup/* -mtime +10 -exec rm {} \;

Не делайте так. Это очень-очень плохая идея.
Поясню, если у вас по той или иной причине бэкапы не создавались/создавались-с-ошибками-читай-не-создавались в этот период, то есть не иллюзорный вариант остаться вообще без бэкапов.
ЗЫ fyi для удаления у find есть ключик -delete можно без -exec обойтись.

Полностю соглашусь с вами. Но, во-первых, это тестовое задание, т.е. случай немного искусственный. Во-вторых, можно «из коробки» удалять бекапы по TTL, но мне «резало глаза» , что все бекапы свалены в один каталог. Такая вот глупая эстетика, может оно не нужно и проще сделать ls -a, но душа моя требует аккуратно разложить в директории :-)

Для 10 архивов разницы не заметите. А вам о другом говорят, что автоматически удалять, не проверив, а остались ли вообще архивы не следует. То есть условие будет: надо оставить 10 последних, а остальные удалять. Тут find особо и не применишь.

Это понятно, что IRL нужно обязательно проверять, а есть ли вообще какие-то бекапы.
