I currently use a program called copywhiz on windows that backs up any files or directories created after a certain date to a usb hard drive and runs once a day.
I want to transition fully to Linux. Is there any easy to use software that works on Linux that can do this?
P.S. I have tried creating a bash script to do this but for some reason it has trouble with the date part. So a software solution would be prefered.
I'm curious to know more about your "certain date" requirement - this sounds like it might be an XY problem. As for general advanced backup programs, I have two easy recommendations that are similar in featureset:
The most important parts of real backup software IMO is the ability to compress your backups, version your files with rolling/pruning snapshots, and version your files efficiently with only deltas between them taking extra space. You can also encrypt your backup if you want to store it with a remote party, or run integrity checks to check for bitrot.
Yeah, with those options it's easier to back up your whole home directory, and then daily backups only take a minute or so and a small amount of additional space to back up what's changed since the day before.
2nd'ing Vorta+Borg. It's also really easy to find off-site backup options compatible with Borg. I'm using BorgBase, which offers ridiculously cheap storage, the choice of EU and US destination, and supports the development of both Vorta and Borg.
I’m pretty sure there are lots of options that work great. I personally just use rsync-but I know the command line is scary for a lot of people making the transition. There are lots of options like timeshift that basically put a gui wrapper around rsync. I’ve seen a lot of love for borg as well - maybe try one of those two.
I feel backups are personal and it’s hard to get a “just do this instruction”. You’ll probably have to pick a product, and then do some homework to see if it can do what you want. This is further complicated by the distro you use - or more specifically if your distro uses btrfs. Some people use a backup as a sort of snapshot, and btrfs is more full featured than ext in that regard.
Timeshift is for a system backup, in case your system broke for whatever reason you could get back quickly to your work without rebuilding and reconfiguring it.
It's not ment for backing up user files.
Use timeshift, install it, just chose where you want the backups to be installed, preferably a second HD or SD Flash. Chose when like once a day, week at start up for instance and forget it. Then if you screw up your Linux, just start in console mode, timeshift --restore and five mins later your up and running.
If you want just your data to be copied, then Cron
Both are standard Linux programs, often already installed depending on what Linux you have
UPDATE: The specific date thing is because every 6 months i backup my nas to LTO tape so this backup is anything that isn't currently on tape just in case the NAS dies between backups.
You said you run it daily in the post, but now it's every 6 months. You really should be more specific. I for one don't understand why you can't just do rsync -au /source /target
Have you looked into using software meant for tape backup for that? It should back up only what's been changed/added since the last tape backup was done.
Pika Backup. It's very easy to use, you select the directories you want to backup and the ones you want to exclude, then your job is over. Every time you ask it to backup it will add the new and changed files to the backup without deleting the old ones. This way the backups only grow with what's changed.
You can also ask Pika to schedule automatic backups, or you can ask for one manually if the USB HDD is not plugged in all the time.
I use a service called iCloud which has both cloud storage and local backup support built into it. Not free or open source but no cloud platform fully is. It's also really cheap for students.
I use Syncthing to do a similar thing. I jus have Syncthing pointed to nfs mount to my Nas. Any files synced to the folder via Syncthing just end up on my Nas.
Don't consider this a backup. Yes, it could help you survive some failures, but if you simply delete a file by accident on your computer, it'll get deleted from your NAS as well.
