💖 CDRESTORE 💖 — cdrestore(1), bestie edition 🎀

okay so before we even get into it: this is the manual page for cdrestore, section 1 of the manual. she's a real one. let's go ✨

✨ NAME ✨

cdrestore — streaming restore from CD-R(W)/DVD-R(W) 🦋

---

🌸 SYNOPSIS 🌸

cdrestore [-qvDFRTV] [-d device] [-i image] [-l size]
          [-t track] [-c command]

like. that's the whole vibe. now let's unpack her 💅

---

💫 DESCRIPTION 💫

cdrestore is a utility that does streaming restores from CD-R(W)/DVD-R(W) disks. no cap.

and here's the slay part: she's designed to work with any backup tool that can restore from stdin — think tar, cpio, afio, the whole friend group. so if your backup tool eats stdin, cdrestore feeds her. periodt. 💖

---

🔥 OPTIONS 🔥

she has OPTIONS. many of them. we're listing every single one because that's what a bestie does 👑

• -d device — the device name used for reading the backup. (default: /dev/cdrom) 💿
• -i image — enables virtual image mode. the backup stream gets read from the given image file instead. bestie, you have to use this one if you're restoring from a dumped image too. (default: none) 🫶
• -l size — specifies the media size. lowkey important to know: this value is only used to display the free space on the media. that's it. by default the given value is taken as megabytes, but you can append a single letter to pick your unit:
  • k — kilobytes
  • m — megabytes
  • g — gigabytes
  • s — sectors

like 170k, 4488m, 350000s. (default: 650m) 📏

• -t track — the number of the data track on the media for reading the backup. (default: none) 🎯
• -T — enables test mode. the complete restore process runs to test data integrity (includes a CRC checksum test, if available), but no data is output. it's giving "just checking".

NOTE: this only verifies that the data is readable by cdrestore at all. it does not guarantee that your backup software will be able to do a real restore with the data. 😭 read that twice.

• -F — forces cdrestore to begin the restore in the middle of a multi-disk set. useful if you lost a disk or one of them is badly damaged.

NOTE: this will most probably start the restore in the middle of a file. it's up to your backup software to sync to the beginning of the next file. so like, no promises, bestie. 💀

• -R — disables the kernel readahead for the CDROM device during the restore process. (see cdbackup(1) Known problems) 🧚
• -c command — the command that gets executed whenever cdrestore needs to request a new media for multi-disk backups. this command (or script) should prompt the user and return after the device is ready again. she receives one argument: the device name passed with -d. which means you can use it to issue commands to the device, like ejecting the media. iconic. (default: use internal diskchange prompt) 🎀
• -q — queries the media, prints out the contents, and exits. a little look-see. 👀
• -v — enables verbose mode. she talks more. 🌈
• -D — enables DEBUG output (probably not useful for normal use, ngl). 🐛
• -V — prints out version information and exits. the "who even are you" flag. ⭐

🌟 EXAMPLES 🌟

Query the 700 MB media on /dev/sr0:

cdrestore -d /dev/sr0 -l 700 -q

Restore a tar archive to the current directory from track 2 of a 702 MB media on /dev/scd0:

cdrestore -d /dev/scd0 -l 702 -t 2 | tar xf -

Query the contents of a virtual image:

cdrestore -i /tmp/vimage -l 4488m -q

Check data integrity of track 3 in a virtual image after dumping it to DVD media:

cdrestore -i /dev/dvd -t 3 -T

ate. no crumbs. 🍓
