BH 3.0.1 and backup issues

[AlexWilMac]

Is it normal that, using 3.0.1 full backup command of the image:
1) at the end of the process always gives these warnings or errors:

"Create: splashdump
dump not possible, splash will be downloaded later
Create: initrddump
dump not possible, splash will be downloaded later"

and, after the lines regarding some files downloaded, there are other lines reporting
Collected errors downloading various packages
.....3rd-party-settings/Packages.gz, wget returned 1
.....3.0.1/vuduo2/all/Packages.gz, wget returned 1
.....3.0.1/vuduo2/mips32el/Packages.gz, wget returned 1
.....3.0.1/vuduo2/vuduo2/Packages.gz, wget returned 1

and this happens always.

2) it creates only 5 files:
-initrd_cfe_auto.bin
-kernel_cfe_auto.bin
-splash_cfe_auto.bin
-reboot.update
(these ones are the same it creates with previous 2.1.x. images)
-R78SI5~W of more than 200 Mb, which is new, never seen in previous BHs
and there is no root_cfe_auto.bin, the main file in previous BHs
?

It seems to me that this R78SI5 file is the temporary file that shuold then finalized into the missing root_cfe_auto.bin.
The first time I hadn't noticed this fact and I used what Backup had produced to reflash 3.0.1 but it got stuck at the reboot.
Now I fear I'll have the same problem if I try to reflash with these files.
