Good backup software?
show user profile  Dr_Jim
OK....

I'm reconfiguring my storage workflow and now have 2 primary work drives. Each one is a 4TB RAID 0

I want to back up each of these nightly to its own 8TB RAID 1 backup drive.....so thats:

Backup 1: Primary 4TB RAID 0 drive 1 backs up to its own 8TB RAID 1
Backup 2: Primary 4tb RAID 0 drive 2 backs up to its own 8TB RAID 1

I would like these to of course be 'changes only' backups....and also I do NOT want the data compressed. I want it accessible.....if a primary drive goes down I want to be able to simply plugin the backup drive and be working. And since the Backdrives are RAID 1....if one of those go down im still covered.

What software will accomplish this and be low-overhead on my system.
I've used acronis in the past and it was a nightmare. Not even looking in that direction.

Thoughts guys?

Im not an IT guy so theres probably better methods... but i backup about this amount of data regularly. Synctoy is great if you want something very simple which is automated .

I personally prefer to backup manually so i use teracopy now. Basically like windows copy but only overrites files with a newer modification date. I find this a bit better for me as i can copy 4tb data over and takes about 10 minutes sorting through new items and updates them. Im a simple man, i like simple methods.

Thanks man......I wish I could rely on myself to consistently backup manually; but I cannot.

So I need something like you describe, only automated.
It needs to be seriously reliable as well. This is client work.

Am I missing something?
What software do you use Kurt?

You're not just considering a RAID to be a backup?......Explain it to me in my old age....

I use a sharkoon 8bay raid system that is separated from my workstation.
The raid is a failsafe for the drives
Next to that i have a synology diskstation that provides nightly backups.
Next to that i do manual backups on disks i store 'elsewhere' than home just in case.
This should cover any and all possible loss of files.

"Next to that i have a synology diskstation that provides nightly backup"

How does it do this? Is it built into the device? or is it software you run?

Dr Jim I think I missed on something here- you are going to configure 4 drives? 2 pairs of raid 0, as a single raid 1 on top of that?
Anyway, what kind of hardware do you use for all this raid setup? I was told once that a regular mobo can only handle one raid setup (I have a single raid 1 on my workstation and I also use the syncback pro software).

Totally unrelated and of no use:

RAID = redundant array of independent disks = sacrifice a hard disk to gain redundancy for when a hard disk fails.
RAID1 = mirror = write to 2 hard disks in parallel. increases read speed slightly. You sacrifice 1 hard disk to gain redundancy.
RAID5 = 3 or more hard disks. write in stripes. parity bit is used to calculate missing data if a hard disk fails. slightly faster read/write. You sacrifice 1 hard disk to gain redundancy.
RAID 5 hot spare = sacrifice another hard disk to allow for a 2nd hard disk failure.
RAID 6 = JFGI

RAID only offers redundancy against hardware failure and does not protect against data loss (fire, flood, theft, virus, accidental deletion).

RAID only works if you detect in time that one of your hard disks has failed - if you fail to notice and a 2nd hard disk fails you may be in trouble.

Backups should ideally:
a) be full, not incremental and not use compression
b) occur when your data set changes significantly (daily, weekly)
c) occur depending on how far back you want to be able to restore data from (monthly, yearly)
d) be kept off-site (to protect against theft, flood, fire)
e) be kept offline (to protect against cryptomalware or viruses wiping your NAS). At leat keep it in a different room and if NAS, connect it to a different power circuit / UPS).

Businesses still like tape backup as you can store the tape cartridges in a safe location off-site. I don't like block based backup (inventory - catalog - restore) I like file based backup and simply use 2 removable USB hard disks and rsync (linux) or robocopy (windows). I disconnect and store when not backing up. You have to be aware you can't backup locked files (i.e. you can't easily backup the Windows operating system as a whole just like you can't fix your car while you're driving). Always do a test restore as nothing is worse than discovering your backups are no good when you need them most.

You only backup data. There is static data and dynamic data. Static data you archive for future reference. Dynamic data (data that changes frequently) you backup.

I like SpaceSniffer to quickly scan a partition or top level folder to see where most large files live.

Hey Dr Jim, yeah sorry, the DS is basically a linux server that can run all sorts of things like media, camera surveilance,webservers anything really. It comes with a great os that you can acces remotely. The software is called backupstation and really does what it should do.

All info, screenshots are there
https://www.synology.com/en-global/products/DS1515+

You also have smaller and bigger versions to suit your needs AND they are expandable, just add one = double capacity etc

I have 2 running one for personal use and one for work
Might add a larger one soon https://www.synology.com/en-global/products/DS3615xs

Robocopy *source* *destination* /mir

Create a batch file, run it manually or set up a schedule in windows scheduler.

/Mir command only copies files that have changed since last run.
and you can add a >>logfile.txt if you want a log.

Terribly boring signature.

its true robocopy is very useable!

But sometimes its nice to have a UI I find.

Soontekk we have a synology rack(station?) at work and it's quite friendly. But I wanted to backup from another server to IT and it didn't seem possible! I was surprised (and grumpy) about that.

Keep considering getting a normal one for home...

Strange reevers, i do all kinds of copy operations to it without problems.
Make sure your user admin rights are set correctly and all should go swimmingly.
