I‘m using rsnapshot filesystem snapshot utility to make incremental snapshots of local and remote filesystems for 10 production servers running on RHEL 5.x system. The rsnapshot commands makes extensive use of hard links,
so if the file doesn’t change, the next snapshot is simply a hard link to the exact same file. How do I use the rsync command to copy my the entire snapshot directory /raid6/rsnapshot (around 4TB) to a remote server?

I‘m using the date +’%D_%T’ to store Unix system date and time in a shell variable called $_now:
_now=”$(date +’%D_%T’)”
echo $_nowOutputs:
01/20/12_16:10:42
I’d like to replace / and : with _. I’m aware of the following sed command:
sed ‘s/\//_/g
> s/:/_/g’ <<<"$_now"Outputs:
01_20_12_16_14_09
How do I specify two pattern within the same sed command to replace | and : with _ so that I can get output as 01_20_12_16_10_42?
