I use time machine for our Macs at work, each has their own backup. One computer is the main computer with all our data and it is backed up regularly via time machine. I want an offsite backup as well. I bought a device... well pre ordered that will let me plug in an external hard drive at home and be able to connect to it at work like a normal external drive. So I want to have 2 time machine backups, one to the local drive that will be connected and the other to the offsite drive that will be connected. Does MacOS allow me to do this?

I will say I am not stuck on having it done by time machine for the offsite backup. I am open to options for daily automatic incremental backups if there is something else that will do this.

thanks

My gut says it would be painfully slow, both in setting up the backup and restoring. Can't say for sure if it will work; but if you do manage it, I suggest you selectively backup (i.e. blacklist everything but Documents)

Other simple options would be rsync or CCC.

I would strongly caution against using Time Machine for mission-critical data. It's unreliable at best, and prone to database corruption. I've seen many people burned by its failures.

Install an encrypted backup service like Backblaze, which will keep an offsite copy of data up to date. You could use Time Machine as a local/extra backup.

Have been using Time Machine since its inception and thankfully no issues yet. I will keep that in mind. I do want to control the backups myself, I do have what I need for offsite backup just want/need an app that will do it automatically. I don't want to have to remember to manually do backup, just set it and forget it.

I am sure it will be slow the first time, though I think I will be able to do the initial backup onsite and then let it do incremental backups after that as it is supposed to act like an external drive even though it will not be on site.

I have never used CCC, but heard many good things from people. Does it have automated backup options?

Backblaze is automated and off-site for your needs. It's pretty inexpensive, too.

Not just the first time. IIRC the image file needs to be mounted each time to do the backup/restore. It'll be slow every time, and slower as the backup size grows.

Not just slow in the processing. Remember Upload speeds are about 10% of your download speed, not to mention the amount of bandwidth that would be consumed.... YMMV.

I am not worried about bandwidth, have unlimited at work with 60 down and 10 up. Home I have 100 down and 20 up I believe. I am going to look at CCC. I have all the hardware so paying someone else to host it and adding a monthly fee, albeit small, is just not something I want to do right now.

Off topic... When I was looking at the back blaze website I noticed they were using pretty antiquated Macs there. Those old G5's or early Intel C2D macs. Think it might be time for an upgrade!

Maybe they're trying to show that even companies that can't afford to update their iMacs can afford their service, and at a consumer price. ;) :D

Yes, you can choose more than one volume for Time Machine backups. Open TM preferences, choose "select disk", then "add disk", it will list your TM backup volume as well as any available volumes. When you add a volume, it will present you with the option of alternating backups using both.

Good luck!

Thanks! I am going to go with the CCC option and just backup the data folder. I do not need apps backed up or the OS as that is all looked after by Time Machine and even if it was not, that is the easy part. I also don't need an hourly backup like Time Machine will probably have it run once a day in the evening when no one is around.

Thanks for all the suggestions and help everyone, much appreciated.
