Backup to SD card: File too large, "Error: cannot load"

Bug Reports
#1

REPRODUCIBILITY: 100%
OS VERSION: 4.5.0.19
HARDWARE: Xperia10 II - Dual SIM
UI LANGUAGE: English
REGRESSION:

DESCRIPTION:

When trying to create a backup on a VFAT formatted SD card, this fails if the compressed size of the backup would be more than 4GB (the file size limit for VFAT).

This is not tied to a certain OS version.

PRECONDITIONS:

SD card, formatted to VFAT. VFAT seems to be the only option for access from Sailfish OS as well as Windows.

STEPS TO REPRODUCE:

  1. Start Backup to SD card
  2. Wait…
  3. Receive error message “Error: cannot load”

EXPECTED RESULT:

A working backup: tar.gz splitted over multiple files.

It would be even better to have the old backup program where the user could choose which parts to back up. (E.g. it seems pointless to me to save the same camera pictures to tar.gz again and again instead of just syncing them or doing an incremental backup.)

ACTUAL RESULT:

“Error: cannot load”

MODIFICATIONS:

none

Well you have only an option, format your card as ext4 which is a filesystem with no such limits

You can read it then, only on linux but this has nothing to do with jolla nor sailfish, it’s just how microsoft designed vfat (or fat64)

I think the “bug” part of this is that SFOS backup doesn’t provide a clear enough error message. “Error: cannot load” would make me first think the SD card was full or faulty until I remembered that “ya, vFat and FAT32 have a 4GB file size limit” which can take a while to dredge up in my brain that’s been filled with many other things since the last time I had the problem.

Your expected results, OTOH, actually sound like a potential feature request. Either doing a rar-like multi-file backup or implementing a differential system like you suggested. I dunno if those are a great requests or not, but I’m not here to judge that.

But lastly, at some point SFOS seems to have acquired exFat support. When I use a factory-fresh SD card > 32GB formatted that way, the OS mounts it ok, both in the card slot and via USB reader. I don’t think I’ve added any packages containing exfat support, but there it is. So that might be your solution/workaround.

Thanks. I’ve formatted to exFAT now and the backup did work. The TAR file size is 4.08GB.
Backing up, formatting, copying back took some hours for the 400G card.
