logrotate-备份任何文件

Question

I have one file. It's not a log file. Every day I need to copy it somewhere else adding timestamp to its name. I need to keep last ten (10) days copies. I am considering using logrotate service (server is running CentOS).

My question is if there is some limit on logrotate to rotate only log files or if I can use any other file and location. That is may I specify some other location where to put copies with timestamps and to hold only last 10 (days) copies?

Thanks in advance for your hints.

You can rotate any file in any location eg take a look at /etc/logrotate.d/samba (if installed) which rotates log.smbd . Just create a new file in /etc/logrotate.d/ and configure for your file to be rotated. A nice description is here for centOS not different ( here ).

The problem is the timestamp in the name. If you want this it is no longer rotating . With logrotate the latest archived file is always number 1 and thus all older once are getting renamed. But they keep their time of last modification stored in the file system untouched. But this time is not in the name.

As an alternative you can just create a new cron job by adding a file in one of the \\etc\\cron.*\\ directories. This cron job can move you file adding a timestamp eg by using date +%y%m%d_%H:%M and create a new file using touch . No need for logrotate .
