当我尝试使用Percona innobackupex执行备份时,我收到以下错误:
george@db-pxc-1 [~] [17:50] sudo innobackupex --user=root --password=secret --host=127.0.0.1 ~/Data
160830 17:50:34 innobackupex: Starting the backup operation
IMPORTANT: Please check that the backup run completes successfully.
At the end of a successful backup run innobackupex
prints "completed OK!".

xtrabackup版本是:
george@db-pxc-1 [~] [17:58] xtrabackup --version
xtrabackup version 2.3.3 based on MySQL server 5.6.24 Linux (x86_64) (revision id: 525ca7d)
Perl版本:
george@db-pxc-1 [~] [18:03] perl -MDBD::mysql -e 'print $DBD::mysql::VERSION'
4.016
服务器正在运行Debian Squeeze。我一直在ubuntu机器上使用此命令来执行备份,之前从未遇到过问题。
MySQL不是PXC,而是普通的Percona服务器。我有足够的磁盘空间和内存。

innobackupex:与linux文件限制配置有关。
提高文件限制,然后重试
$ ulimit -n 999999
