Weirdly enough, the file header is partially identical between different files and contains the words “whatever” and “CONSOLE”. But if I try to read a file, it fails because instead of the actual file contents, all I get is some gibberish. I can see the file tree and browse it just fine.
#Bootable linux fldigi android#
I want to backup my Android SD card so I inserted it to my computer (tried multiple ones by now). The card is broken beyond repair and all files are lost. I might be able to salvage some of the files by using Android’s share functionality but there was nothing important on the card so I won’t bother trying. Trying to rsync or ddrescue the card’s contents using a separate devices led to stalls and read errors. The internet says it is typical for SD cards to go read-only as a symptom of fail. I can’t read file contents from my Android SD card on Linux and it’s weirdĬonclusion: The files are encrypted with Android’s file-based encryption. This entry was posted in linux, small things on by Hannes. If you want to restore your server because of a breakage, just boot it into rescue mode and do the same as above otherwise.
cat .gz | ssh "gunzip -c | dd of=/dev/sda1 bs=1M status=progress conv=fsync".Create a new server using the same or a similar configuration as the backed up one.If you do not need your server to be live during backup, you can skip the snapshotting and second server of course, just boot your server in rescue mode instead. Don’t be stupid, do it twice and compare the checksums.You might want to use xz or zstd instead. Of course the ratio between remote CPU compression speed vs download bandwidth depends on your specific situation. gzip (with the default compression level) kind of maxed out the server CPU but still enabled me to almost max out my download bandwidth.The bs=1M is fairly random by me, worked well, didn’t care to optimize.ssh "dd if=/dev/sda1 bs=1M status=progress | gzip -" | dd of=.gz bs=1M.
#Bootable linux fldigi archive#
Use good old dd and gzip to image the main disk to a local archive.Consider imaging the whole device instead of just a partition. Pay special attention to your own partitions and make sure you archive what you really need. Make sure you understand everything before you attempt this. standard CX11 servers with default images.
#Bootable linux fldigi full#
Here is how I create full disk backups for e.g. Unfortunately they do not let you download backups and snapshots of cloud servers locally. Hetzner is a nice, cheap host for server.
