Unable to backup with RSync

[fabiobiscia]

Hi, i’m running into some issues with rsync. I need to backup my entire NAS (user folders included and not only shared folder, this is a huge limitation for USB-COPY) to a USB hard drive. Backup starts without problem, usually next to the end of process rsync with verbose activated, report “I/O error 5” and after "failed verification -- update discarded (will try again)". After this problem the entire NAS seams corrupted, files disappear and the web gui interface say: “raid error” (my f2-210 is a RAID 0). After reboot, I checked file system on both sides and everything is good, files come back. How it’s possible? There are other solutions to backup the entire NAS to a USB drive smoothly? I post my script for backup and errors photos, i plan to use it (without verbose) as crontab.

Best regards.

Code: Select all

#!/bin/bash

umount /mnt/pom; mount /dev/sdb3 /mnt/pom &&

readonly SOURCE_DIR="/mnt/md0/User"
readonly BACKUP_DIR="/mnt/pom/TNAS_backup"
readonly DATETIME="$(date '+%Y-%m-%d_%H:%M:%S')"
readonly BACKUP_PATH="${BACKUP_DIR}/${DATETIME}"
readonly LATEST_LINK="${BACKUP_DIR}/latest"

#mkdir -p "${BACKUP_DIR}" &&

rsync -arvHu --progress --info=progress2 --delete \
  "${SOURCE_DIR}/" \
  --link-dest "${LATEST_LINK}" \
  --exclude=".cache" \
  "${BACKUP_PATH}" &&

rm -rf "${LATEST_LINK}" &&
ln -s "${BACKUP_PATH}" "${LATEST_LINK}" &&
readonly ENDTIME="$(date '+%Y-%m-%d_%H:%M:%S')"
java -jar /mnt/md0/User/admin/home/emailSender.jar Backup effettuato correttamente il "${ENDTIME}".
umount /mnt/pom;

After failed Backup I tried to list files in /mnt/md0 and this is the result:

Code: Select all

root@TNAS-BM:/mnt/md0# ls
/bin/ls: reading directory .: Input/output error

One of your drive might get faulty. Please remove it from the tray and insert it again. Or you have to have full scan your drive by following the instruction viewtopic.php?f=75&t=1125

Thanks for your reply, perhaps I have solved this ridiculous problem.... after 6-7 backup I noticed that all were stopping after a specific video file, i opened this video file and it was corrupted. I don't know if the video location was broken or the file itself but it's really annoying that rsync broke its process due to a corrupted file and abort all later processes. I'm trying another backup, I will update you if all work fine.
