When updating (sudo apt-get update) sometimes a package will ask if I want to overwrite an older configuration file. I have occasionally pressed 'D' to see the differences between the two files. But...

Thanks for the replies.

Can you evaluate this backup system for security risks?

I’m new to linux and trying to form a good backup system.

I have a program that writes backups to a sshfs mounted drive. This drive is...

I could not get chown to work either. Here are my commands:

from within /home/local-system/Desktop/:


mkdir 777 backups

Thanks sandyd. I think I understand what I am missing now.

I tried idmap=user and thought it meant for me to put the intended user's name in for "user", but instead it maps to the current user. So...

I am trying to mount a drive using sshfs and give access to another user and group (think something like apache). I use this command:

I successfully got most things working and I think I understand everything much better now.

To be clear on some things, if I wanted to log into the server via SSH from some new machine but did not...

This was all very helpful! I am going to run through it all again right now.

rsync was something I hear about frequently.

Can I rsync the server while it is running? Can I rsync individual files while they may be opened?

Ok, I will just continue to try to mount without it for now. Thanks.

And openssh-server will only be installed on the server side.

Why is this


sudo gpasswd -a $USER fuse

important for sshfs?

It says to do it here, but I can't figure out why: https://help.ubuntu.com/community/SSHFS

The following commands...

What would be a good way to backup 1) a whole server, and 2) individual files on the server?

For 2), I had the idea of creating a remote mount on the server and then copying files into it and then...

Thanks, I will try these solutions.

I am trying to remove the text file logs after compressing them with logrotate.

I successfully have the log moved to a folder for old logs using the olddir setting, and compressed to a logname.gx...

If I can provide any more information that might help, please let me know.

Thanks for the help. Setting the rotate option to a very large number is what I ended up doing.

I am testing a logrotate config using the debug flag:


logrotate -d [path_to_config]

if I use


sudo logrotate -d [path_to_config]

Thanks. Unfortunately the man page did not say. I expect it either defaults to something, or if I am lucky, doesn't put a cap the rotation, but I am completely unsure.

Thanks.

Would you happen to know what happens if you leave out the "rotate" parameter all together? This was my first guess, but I can't find it documented what the default is if this is left...
