Duplicate of https://github.com/rdiff-backup/rdiff-backup/issues/11 and/or https://github.com/rdiff-backup/rdiff-backup/issues/38 - rdiff-backup has definitely some limitations when it comes from backing up files from one file system to another one with less features. We'll look into it once the code is cleaner.

filesystem quoting on this filesystem is not well supported. Once we get python3 support working everything will change. postponing for now.

Moreover: the filesystem for source data is ext4.

The target filesystem is VFAT.

I'm running Synology DS214play with Debian chroot. Inside chroot I have mounted the /homes filesystem where my 800GB data is, and /volumeUSB2 device, where I have WD Passport 1TB external drive. I'm attempting to backup 800GBs to 1TB drive.

I use DSM 5.2, and inside of Debian chroot I've installed rdiff-backup.

I run it like this:

diff-backup --exclude-symbolic-links -v5 /home/wkoszek rdiff-backup.20151013

root@wkoszek_nas:/mnt/volumeUSB2# mount
proc on /proc type proc (rw,relatime)
sys on /sys type sysfs (rw,relatime)
none on /dev type devtmpfs (rw,nosuid,noexec,relatime,size=355860k,nr_inodes=88965,mode=755)
none on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620)
/dev/mapper/vg1000-lv on /home type ext4 (rw,relatime,user_xattr,synoacl,barrier=0,journal_checksum,data=writeback,jqfmt=vfsv0,usrjquota=aquota.user,grpjquota=aquota.group)
/dev/sdt1 on /mnt/volumeUSB2 type vfat (rw,relatime,uid=1024,gid=100,fmask=0000,dmask=0000,allow_utime=0022,codepage=default,iocharset=default,shortname=mixed,quiet,utf8,flush,errors=remount-ro)

I get Invalid argument failure, since rdiff-backup doesn't like the filename. Attached are the details.
