Your server does not support command line ZIP

[henry]

I was using backupbuddy for backup all my WordPress blog.
However, during time of backup process, it prompted this message as below.

Your server does not support command line ZIP. Backups will be performed in compatibility mode.
Directory/file exclusion is not available in this mode so even existing backups will be backed up.
You may encounter stalled or significantly delayed backups

Then, shown a link

The command line:
# yum install zip
# sudo apt-get install zip unzip

Is this alright to run on KloxoMr?

I think I have no problem about the min.requirement stated over there.

Code: [Select]

# yum install zip
