Как исправить ошибки rsnapshot при бэкапе с VDS под KVM?

Question

[Антон]

Debian-сервер wheezy 7.5, делается бэкап с vds на KVM при помощи rsnapshot. Логи завалены ошибками.

Попробуйте увеличить детализацию лога, установив более высокие значения директив:

verbose         2
loglevel        3

Answer 2

[Антон]

verbose 4
loglevel 4

Тоже самое и пишет, в остальном добавился только вывод копируемых директорий.

rsync: symlink "/home/liquidspace/YaDisk/_backup/vds/auto/daily.0/localhost/etc/dictionaries-common/default.aff" -> "/usr/lib/ispell/american.aff" failed: Function not implemented (38)
rsync: symlink "/home/liquidspace/YaDisk/_backup/vds/auto/daily.0/localhost/etc/dictionaries-common/default.hash" -> "/usr/lib/ispell/american.hash" failed: Function not implemented (38)

Мне сложновато понять о чем говорят эти парни но вроде как до 2007 года в линухе не было поддержки некой функции lutimes(), и товарищ с аналогичной проблемой как у меня запускал билд rsync сделаный на одной системе с новым glibc на системе где такой функции нет. Мой Debian 7.4 wheezy вроде бы в феврале этого года вышел, свежий же.

Запускал из под своего пользователя liquidspace: sudo rsnapshot daily. Теперь запустил под рутом su, rsnapshot daily и получил ошибку:

root@cascade:/home/liquidspace# rsnapshot daily
Setting locale to POSIX "C"
echo 21112 > /var/run/rsnapshot.pid 
mv /home/liquidspace/YaDisk/_backup/vds/auto/daily.1/ \
    /home/liquidspace/YaDisk/_backup/vds/auto/daily.2/ 
----------------------------------------------------------------------------
rsnapshot encountered an error! The program was invoked with these options:
/usr/bin/rsnapshot daily 
----------------------------------------------------------------------------
ERROR: Could not rename("/home/liquidspace/YaDisk/_backup/vds/auto/daily.1", "/home/liquidspace/YaDisk/_backup/vds/auto/daily.2")
ERROR: Error! safe_rename("/home/liquidspace/YaDisk/_backup/vds/auto/daily.1/", "/home/liquidspace/YaDisk/_backup/vds/auto/daily.2/")
/usr/bin/logger -i -p user.err -t rsnapshot /usr/bin/rsnapshot daily: \

    safe_rename("/home/liquidspace/YaDisk/_backup/vds/auto/daily.1/", \
    "/home/liquidspace/YaDisk/_backup/vds/auto/daily.2/") 
rm -f /var/run/rsnapshot.pid

Удалил все папки с предыдущими бэкапами, получил:

root@cascade:/home/liquidspace# rsnapshot weekly
Setting locale to POSIX "C"
echo 21257 > /var/run/rsnapshot.pid 
/home/liquidspace/YaDisk/_backup/vds/auto/weekly.1 not present (yet), nothing to delete
/home/liquidspace/YaDisk/_backup/vds/auto/weekly.0 not present (yet), nothing to rotate
/home/liquidspace/YaDisk/_backup/vds/auto/daily.2 not present (yet), nothing to copy
rm -f /var/run/rsnapshot.pid 
/usr/bin/logger -i -p user.info -t rsnapshot /usr/bin/rsnapshot weekly: \
    completed successfully

однако даже папка для бэкапа не создалась.

А скрипт бекапа из под какого пользователя запускаете? Если из-под root запустить, ошибка сохранится7

Подправил ответ выше с логами.
