I'm using a 120gb HD 2.5" sata in a external USB enclosure. I would like to make backups using this enclosure, but I don't know how to do it in Mint. I heard there is a command line that is the best thing to backup files, because it would only backup modified files. In Windows, there are some softwares to do it. But I don't wanna have to boot into windows just to make a backup.
Does anyone know how can I do it in Mint?
PS - I will make a 10gb NTFS partition, just in case I need to use the enclosure with some PC with only windows installed. The rest I will set to Ext3.
I do all my 'home' (or user-based) type backups using rsync. There is a gui front-end for it called Grsync that is in the repos. It is a very powerful & flexible tool or this purpose. The first time you use it, it copies all the files to the external drive. Thereafter it only copies changes to files, new files and deletes old files. This is all subject to how you set it up. i.e. your command line options or your gui option selections.
It is important to understand what each of the options actually does so that you end up with the backup results you want. In the gui version it has a nice option to simulate the backup before actually doing it - this is really nice for troubleshooting the options. Don't forget to exclude caches and temp thumbnails etc - otherwise you are just backing up junk. Have a read of 'man rsync' and do some Google searching. There is heaps of stuff on the net about it including example scripts.
Once you have it sorted you can create a crontab entry and have the backups done automatically. Mine run every night here at 4am.
Regarding the drive format, I think you need to think about your usage. Personally, I have left Windows far behind so all my external drives are formatted as ext3. If someone from a Windows world needs access, I set them up as a Samba share - but they operate and are maintained as Linux drives first & foremost.
I think there is a version of rsync available in Windows, but you would have to Google it. As I said, I spend VERY little time in that world anymore.
Hope this helps,
