Stable Backup from SD-Card to iPad or external Storage (HDD, SSD) 2021

megaadmin — Sun, 01 Aug 2021 11:56:44 +0000

With FE File Explorer I was finally able to backup my camera SD card to my iPad or a connected SSD while traveling. The standard Apple Files App is unstable and often messes up backup operations with bigger files.

With FE File Explorer you can easily copy files from SD-card to the iPad opr a connected storage device like SSD or HDD. the app can also access SD cards that are read-only. While copying, we always see the progress for every single file. The app supports differential backups, and asks if we want to skip duplicates or rewrite duplicate files.

Everything you need is a USB C Hub with SD card reader and maybe an external Storage.
I use a SanDisk Extreme Pro V2 for this:

Copy and back up photos and videos from SD card as a backpacker without a notebook

megaadmin — Sun, 22 Dec 2019 17:38:15 +0000

There are 4 weeks of backpacker holidays on Bali ahead of us. To save weight we travel without Macbook and Co., but with drone and camera equipment.

But what is the most reliable way to back up the files from the SD cards on the way?

Small, lightweight helper for fast data backup

We found our solution to this problem in the WD My Passport Wireless Pro 4TB.

The external hard drive can copy files from SD cards via an integrated SD card reader. All it takes is the touch of a button. In addition, the external hard drive can also accept files via wireless connection, which we simply don’t use ourselves. This is because, in my opinion, no data transfer is as fast and secure as via high-speed USB 3.0 connection or directly via integrated card reader.

With dimensions of 12.6 x 12.6 x 2.4 cm and a weight of 450 gr. it fits well into our travel backpacks. The device is about the size of a Discman, so it doesn’t take up too much space in your luggage.

Backup even in the jungle without electricity

The special thing about this external backup solution is the integrated 6,400 mAh battery, which allows us to copy files to the hard disk for up to 10 hours. This enables us to make backup copies of our drone recordings and photos even after days without power supply, thus creating space on our SD cards again.

The integrated battery is, despite the sufficient runtime, still small enough to be taken on board by any airline without any problems and does not add unnecessary weight to our backpacks in our luggage.

Quick backup of the SD card (with a little practice)

The device has two rectangular buttons. While the first button turns the hard disk on and off, the second button controls the copy process from the SD card. If we press the SD card button long, the contents of the memory card are copied to the hard disk.

Depending on how the hard disk was previously configured, either the complete contents of the SD card will be transferred to a new folder on the hard disk 1-to-1, or alternatively only those files will be copied that have been newly added to the SD card since the last backup. This differential transfer mode sounds good at first, but there are some dangers.

If files are transferred from several SD cards from different devices, the backup logic can get confused and possibly not backup data because a similar file with the same name has already been backed up.

Thus, those who back up their SD card to the hard disk and then format the memory card run the risk that the next backup process will not back up the photos created after formatting, as the numbering of the photos might start from zero again.

Some similar experiences of other users can be read in this thread: https://community.wd.com/t/backup-of-multiple-cards-creates-a-mess/216040/25

For this reason the differential transmission is not acceptable for us. We back up the complete contents of our SD cards to a new folder every day. This way the external disk does not get mixed up with the SD cards from two DSLRs and the video drone.

Due to the use of the 1-to-1 copy mode, we naturally use more memory than actually necessary, which is why it only makes sense for us to use the 4TB variant. In order not to run out of memory too quickly, we delete any duplicates manually from the hard disk via iPhone app.

No matter which way we choose, once the data transfer has been initiated, the four status LEDs on the upper side show the progress of the copy process.

Dust and waterproof – if you put it in a plastic bag

The only drawback of the “WD My Passport Wireless Pro 4TB” is the lack of protection against water and dust, which would be of interest during a backpacking trip in tropical climates. As a workaround, we simply pack the hard disk in a sealable plastic bag, as it is also used for liquids in hand luggage. Problem solved.

Restore SD card images reliably with graphical user interface

megaadmin — Tue, 13 Feb 2018 17:34:49 +0000

If you want to restore a previously saved image of an SD card, you can often use various command line tools such as the terminal. Restoration can easily become a pain: The progress of the recovery is not displayed or the recovery is simply unreliable – the SD card in Raspberry Pi still doesn’t want to boot at the end. A new tool for Mac, Windows and Linux with graphical user interface solves the problem: Etcher.

If you use your Raspberry Pi or other single-board computers in not necessarily gentle environments, you know that the file system can suffer unpredictable power fluctuations. Often only a restore of a previously (hopefully) made backup or the repair of the SD card’s file system on a Linux host will help.

However, as I usually have current backups and only rarely use the log data that has been generated in the meantime, I usually use the SD card for this purpose. And that’s a pain in the ass every single time.
The image does not fit to the physical size of the SD card, the image was written unreliably (checksum error) and in the end my Raspberry won’t boot from the card. All over again…

This is over now, because there is a new tool now: Etcher is an open source program for reliable recovery of SD card images with graphical user interface. It not only recovers the SD card from ALL common backup formats (. gz,. zip,. img etc.), it also checks the target card and configures it accordingly and then verifies the written image.

If Etcher says that the image was written successfully, the SD card will work in the target device. You can count on it.
You can find the excellent tool here: https://etcher.io/

Remote Backup your Raspberry Pi with SSH via Terminal

megaadmin — Sat, 02 Dec 2017 08:03:20 +0000

Backing up the SD card of the Raspberry Pi is really time consuming. Switch off the Raspberry, remove the card, insert the card into the computer, create an image of the SD card, switch the card back into the Raspberry, switch it on again. Lots of manual work and downtime for the duration of the backup. Reason enough to do it all remotely via terminal session. These are the instructions for creating and restoring the backup. Works for backups of SD cards on any Linux system.

Create Backup

Open the terminal session and fire the following line, adjusting the red parts (IP address of the raspberry and file name of the backup):

ssh pi@192.168.10.11 “sudo dd if=/dev/mmcblk0 bs=1M | gzip -” | dd of=~/Desktop/backup_2017-11-14.gz

The system then asks for the given password for the user “pi”. Enter the password and then WAIT FOR A LONG TIME, even if the system does not display any updates during the process.

Fun Fact: If you are on the Mac, you can check the current status of your backup with “CTRL”+”T”. You can press the combination infinitely often during the transfer to display the transferred bytes.

When the backup is complete, your input line will reappear in the terminal.

Restore Backup

Recovery does not work remotely. After all, the system would be flattened at runtime. It would be exactly like cutting the famous branch you are sitting on. If that was possible, it would be an security risk. Here you really have to grab the card and create the SD card from the backup on an external system.

Open the terminal session and fire the following line, adjusting the red parts (target disk {SD card} and file name of the backup):

diskutil unmountDisk /dev/disk1
gzip -dc ~/Desktop/backup_2017-11-14.gz | sudo dd of=/dev/rdisk1 bs=1m conv=noerror,sync
