Hi,
Just to make sure I'm doing this correctly. This is the line I added in cron and its supposed to backup the MBR and partition information onto the sdcard weekly at 3 AM sundays with a timestamp in the filename. I tested it manually and it worked. Would this line work in cron?
00 03 * * 1 dd if=/dev/sda2 of=/storage/backup/mbr_sicherung_$(date -u +\%Y\%m\%dT\%H\%M\%S) bs=512 count=1
Thanks for the help. I'll look into that.
I don't know how to use these tools though since I have almost no experience with linux. Just to make sure "dd" writes byte per byte to a file, right? So I would do that for the part on the partition where partition data is stored and to restore it I would use the same command to write from file back on to disk?
I suspect the storage too but I never expected this could happen
Hello, I'm new here and sorry if I ask a question that has already been answered somewhere but I did not find anything with google and the search here.
Might be that I used the wrong search terms.
Recently I had an issue where the partition on my RAID5 USB drive got messed up somehow right in the middle of watching a movie. I don't know how or why and if it can happen again. The HDDs and the RAID seem to be fine and the enclosure seems fine too. Anyway after that I suddenly had 2 unformated partitions instead of 1 NTFS and recovery tools would take like 10 days because of the size, so I started building my collection over again. But this time I want to make backups of the partition table and not the content on it (Its in a RAID5 for that reason) I found a tool on windows that lets me do that but that would require to plug the drive into my pc every time I want to make a backup.
So my questions are:
1. Would backing up the partition table enable me to restore the partition if this happens again?
2. Is there a way for my pi4 with libreelec to automatically make backups of the partition table?
Thank you
