Grsync questions

I noticed that in Grsync, the boxes for owner and permissions are not checked off.

Is there a reason for that?

Does Backup do the same?

And when a restore is done, are the permissions and owner lost?

If your saving to a Ext4 formatted disk or partition your permissions and ownership will stay in tacked. If your saving to a NTFS or FAT formatted disk or partition your permissions and ownership will be lost. This is Linux foundational.

However, if you restored a file from the Ubuntu mate backup utility (Deja Dup), I believe at that point the file would be owned by the account that you restored it to. Kind of like copying a system file to your home folder, it becomes yours.

Mine are being save to a ext3 hard drive.

I plugged it in on the machine with multiple users and was met with a dialogue saying I did not have the required “permission” to access the drive. I did not understand this as I have pr…

Deja-dup, the backup software included in Ubuntu-Mate make "compressed", "incremental" backups - you need a copy of deja-dup to access the backup again. With grsync you can make an uncompressed backup that you can access from any attached Linux computer. My personal backup strategy uses both.
