Okay, I fixed my USB problems discussed in another thread. Now I would like to back up some files. I bought a USB enclosure and a 2 TB SSD (I should have saved $50 and bought one without cache, but I bought the more expensive Samsung EVO 570 instead).
I seem to prefer Linux Mint, although I could probably use Microsoft Backup for Windows 7. I think it still exists. Here's what I did with Mint 18.3 tonight:
and
The linux copy command has a "-u" option that will not copy older files over the top of newer files. But that does not interest me. Now that I did my original backup tonight, I only want to copy those files that are newer, or those that have changed from the copy on the usb enclosure SSD.
I MIGHT be able to use the "find" command with the "-atime" or "-ctime" or "-anewer" or "cnewer" options (which might not work, since both source and destination are NTFS partitions) to get a text list of files, or I might be able to pipe the output of the "find newer files" and copy only those files. Backups would take only a second or two that way.
I MIGHT be able to use the fc command (linux file compare) but I think that is for comparing the bits and bytes inside the file, not the date the file was most recently accessed / modified.
I also have some familiarity with AWK, but not a whole lot.
Or I could just use the "duplicati" add-on tool that should be available as a *.deb package in Linux Mint's repository. Starting it as a daemon (so I can access NTFS drives that ordinary user mike cannot access) should not be difficult, as long as I read up on how to do it.
If I only copy files that are NEWER, like my family budget spreadsheet, backups will take only a few seconds.
Any ideas? Thanks in advance !
