Network – Networking Between macOS 10.6.8 (Snow Leopard) and 10.12 (Sierra)

file-sharingfoldersmacosNetworksnow leopard

For work I have to solve an issue involving very old and new systems. Because of legacy software required for the business, I need to sync folders between Mac A (MBP running 10.6.8) and Mac's B and C, both are iMac's running 10.12 Sierra.

I had been using AeroFS before they shut it down and it worked great. Simple folder mirroring. *I want to mirror folders so there are fewer points of failure, and all files are on each system.

Bittorent Sync (Resilio Sync) would work PERFECT except 10.6.8 is too told to run the client.

What is the best way to mirror folders between these systems? I've considered Dropbox, but due to file sizes and slow internet has been ruled out.

Would a NAS be ideal in this situation? How can I best mirror folders between all 3?

EDIT – Mirroring folders is needed as the MacBook Pro is mobile and will need file access away from the internet.

ChronoSync should be able to do what you want. While they offer an older version that will run on 10.6.8, I would suggest that, instead, you run the latest version on your 10.12 system and use it to sync the files amongst all your systems.

Snow Leopard Server vs Desktop – Key Differences

First off he's wrong on all levels.

The Desktop Version is $29, the Server Version is $500.
A standard Mac Mini is $700 base. Mac Mini Server is $1000 base.

Second, the distributions are pretty much identical. The difference is that the Server Version ships the server applications, tools, and processes. Postfix, Dovecot, Jabberd2, OpenLDAP, the entirety of the /Applications/Server directory, and some of the things in /Applications/Utilites like XSan management and the RAID Utility.

If he's looking to do development for iOS, getting the server version makes no sense. If he's looking to do development for Web Services, it's still easier and cheaper to run it on the Desktop version.

If he's looking to run a server, trivially, for mail services, chat and calendaring services, MORE than just web services (web services are trivially easy on the Desktop Version), then he should get a MacMini Server.

Use a Server for a Server for the features it provides, otherwise, use a standard version.

[edit]
We have two versions of XServes, and two Mac Mini Servers (classic style body), I'd be glad to answer any additional questions you or your friend has.

Function of /home Directory in Snow Leopard

It's got an NFS automounter map mounted on it, so NFS home directories will be automatically available there. Quoting man auto_master:

The auto_master file contains a list of the directories that are to be automounted. Associated with each directory is the name of a map that lists the locations of the filesystems to be automounted there. The default map looks like this:
#
# Automounter master map
#
+auto_master            # Use directory service
/net                    -hosts          -nobrowse,hidefromfinder,nosuid
/home                   auto_home       -nobrowse,hidefromfinder
/Network/Servers        -fstab
/-                      -static

The default auto_home on SL expects to get the home directory-to-machine mapping from NIS or LDAP, but you can add entries manually.

You can remove the auto_home line from /etc/auto_master and sudo killall automountd (which should cause launchd to rerun it with the new map) or reboot. Alternately, add your sshfs mount to /etc/auto_home (and again restart automountd or reboot).
