7zip Benefits: Why Choose 7zip?

Before we dive into usage details, understanding what sets 7zip apart from competitors like Zip, Rar and Tar is important:

Ultra High Compression – 7zip‘s 7z format employs powerful compression algorithms able to achieve ~50% better ratios than other archivers according to multiple benchmarks. This saves enormous storage space and network transfer overhead.

Enterprise Grade Encryption – Securing sensitive data is simple with 7z‘s built-in 256-bit AES encryption which meets top corporate standards. Plus it operates smoothly across Windows, Linux, and macOS for collaboration.

Actively Developed – 7zip remains under active open source development with frequent updates and security patches. The original author Igor Pavlov and contributors are still expanding capabilities today.

Universal Archive Support – Besides its custom .7z format, 7zip handles an industry leading array of over 30 archive and compression formats making it a Swiss army knife. This includes ISO, RAR, DEB, RPM, CAB plus standards like XZ, BZIP2, GZIP, ZIP, TAR and more.

Cross Platform Freedom – As open source software, 7zip guarantees no limitiations on production use cases or worry about licensing issues. Integration is frictionless across most architectures.

Scripting Power – 7z offers advanced automation potential and tight integration paths ideal for programmers and DevOps engineers who need to orchestrate archiving workflows.

With those developer-centric advantages covered, let‘s dig into some hard performance benchmarks demonstrating why 7zip dominates its competition compression-wise.

7zip Compression Performance Benchmarks

Independent tests confirm 7zip is unrivaled when it comes to its compression efficiency. Here are a few studies benchmarking 7zip against other top utilities:

As these benchmarks illustrate, 7zip‘s 7z format outperforms all rival compression options on typical data types – from log files to database dumps across the board.

In particular, 7z achieved over 40% better ratios than formats like Zip and Tar on larger media files in testing. This level of optimization translates into major storage and transfer savings in practice.

Let‘s look at a quick example to quantify possible real-world gains…

Estimated Savings Example

Take a development team that deals with 700 GB of rotating app log, database and config data they need to store and backup compressed.

If using the standard Zip format, the data would occupy ~420 GB archived based on its compression ratio in benchmarks above.

But leveraging 7zip‘s 7z format would allow fitting all 700 GB of logs into just ~250 GB – a 40% or 170 GB reduction!

For cloud-hosted backups especially, choosing 7zip could lower costs by up to $1000s per year. The storage efficiency gains are staggering.

With 7zip clearly dominating compression performance, let‘s get it installed on Arch…

Installing 7zip on Arch Linux

If you followed along in part 1 already, you‘ll have 7zip ready. For those jumping directly here, use pacman:

$ sudo pacman -S p7zip 

That grabs the latest 7z binary package from the Arch repos.

Now let‘s explore some of 7zip‘s powerful capabilities starting with backups.

Backup Automation with 7zip Incrementals

Earlier we demonstrated using 7zip‘s incremental archiving abilities to construct an automated backup solution. Here we will take that further and set up insurer-grade backup processes.

Incremental Database Dumps

To prevent growing backup times for huge databases, DBAs use incremental dumps capturing only latest changes. This avoids re-scanning entire tables wasting IO and compute.

7zip brings this concept to file backups. For example, daily you could archive just new/changed files under /var/log using:

$ 7z a logs-$(date +%F).7z -u logs-previous.7z /var/log

This adds the incremental update of modified logs to the existing logs-previous.7z base archive. Over time as the log folder grows to 1 TB+, sync jobs stay fast.

Local Storage Snapshots

For versioned backup history, a simple formula is running the incremental script above, then making immutable copies:

$ cp logs-2021-08-05.7z /mnt/snapshots  
$ chattr +i /mnt/snapshots/logs-2021-08-05.7z

This efficiently maintains daily snapshots able to restore any historical state.

Off-Site Replication

Finally, securely replicate logs off-server for disaster recovery:

$ rsync -azP /mnt/snapshots username@backuphost:/backups/servers/this-server/logs

Rsync efficiently copies snapshot changes onwards saving bandwidth. Backup data remains accessible remotely in case of failure.

This demonstrates a robust log archiving pipeline harnessing 7zip‘s capabilities – adjustable to other paths like /home. Next we‘ll implement remote backup support.

Syncing Backups to Cloud Servers

While local replication is good, remote cloud hosting brings geographic redundancy for guaranteed recovery when on-site assets are unavailable.

Here is one method to securely automate cloud backups leveraging 7zip archives:

1. Compress Data – Create encrypted 7zip archives of target folders, take care to exclude temporary files not needing backup. This minimizes costs for cloud storage which is priced per GB.

2. Upload via RClone – Use the RClone utility for efficient encrypted transfer of 7z archives onto cloud storage providers like Google Drive, S3, Dropbox etc. This handles parallel uploads/downloads and file hashing for integrity.

3. Lock Archives – Once the backup archive copy is on the cloud, digitally lock it from further changes by removing write access. This prevents corruption ensuring restore reliability.

4. Handle Incrementals – Use the incremental update flag as covered earlier to sync only daily changes rather than rebuilding archives from scratch every time. Much more efficient.

For example, combining the above techniques enables maintaining versioned 7zip daily backups in Amazon S3 for pennies per GB while retaining access performance and secure AES-256 encryption end-to-end.

Automation scripts handle calling rclone for transfers and locking down objects for immutable storage similar to Glacier. 7zip‘s strong encryption prevents exposing unencrypted data.

Professionals trust 7zip for its airtight security standards safeguarding data assets. Read on for more details around encryption options…

Securing Archives with Encryption

Industry expectations around data protection are stringent. Thankfully 7zip answers with military grade encryption capabilities satisfying even highly regulated sectors.

Besides builtin 256-bit AES symmetric encryption, 7zip also supports public key cryptosystems guaranteeing tamper proof archives of sensitive material.

Locking Down Archives

By invoking 7zip through GnuPG, the entire archive can be encrypted and signed using your private key to prevent third party access or modifications:

$ gpg -o secured.7z.gpg -encrypt -sign protected.7z

This requires users have your public key to decrypt. The signature also validates if the archive was altered. Far more secure than basic password encryption which can still expose file names and metadata.

Remote Team Sharing

For securely sharing archives with remote teams including consultants, clients etc, leverage public key encryption.

Simply distribute your public key material and have users first import it locally. Archives encrypted to your key will remain inaccessible without applying the private key held only by you. This guarantees data confidentiality without needing to transmit the actual decryption key over insecure channels.

Between 7zip‘s integrated AES-256 implementation and further public key hardening, even highly sensitive data like medical records, financial documents and source code can be safely archived and synced for collaboration across institutional networks.

Now that we have covered core functionality, compression and security scenarios, let‘s dive into some custom 7zip workflows and tricks…

Advanced Usage Tips and Customization

While 7zip usage focuses around key commands like a for archiving and e to extract, there exist endless ways to adapt its functionality by combining an extensive array of secondary parameters and options.

Let‘s go through some examples of specialized use cases you can mold 7zip workflows around for enhanced automation.

Streamlined Commands

When repeatedly calling the same archive operations, employing aliases helps:

alias 7za=‘7z a -mx=9 -bb1‘ 
alias 7ze=‘7z e -y‘

This presets the -bb switch for super fast archiving and auto overwrites extracted files (-y).

Automating Database Dumps

To orchestrate regular SQL database dumps piped into encrypted archives:

#!/bin/bash

DB_NAME=appdb
DEST=/mnt/backups

mysqldump $DB_NAME | 7z a -si -pfnord $DEST/db-$DATE.7z  

This barrels database output directly into timestamped, password protected 7z containers without disk bottleneck.

Custom File Extensions

Rather than sticking with .7z, you could create personalized extensions like .7app making archives identifiable at a glance:

$ 7z a logs.7app /var/log/* 

Archive Metadata

Embedding custom metadata like versioning or changelog data is possible through text file injection:

$ echo "v1.5 CHANGELOG.." > meta.txt  
$ 7z a -i@meta.txt app.7z /home/app

This stores the text file as comments in archive headers, retrievable later through 7z l.

As you can see 7zip offers many possibilities to craft automated solutions around archiving and compression tailored to specialized needs.

While we have focused so far on command line usage best practices, desktop integration is equally important for intuitive graphical operation…

Integrating 7zip into Plasma Desktop

On desktop focused Linux distributions like Kubuntu operating through a traditional point and click interface rather than the console remains important.

Here we will see how KDE Plasma desktop users can intergrate 7zip‘s powers into the Dolphin file explorer.

Install Archive Plugins

To enable handling 7z and other archives seamlessly through Dolphin, grab the toolbar and context menu plugins:

$ sudo pacman -S ark dolphin-plugins

This adds support for visually compressing and extracting archives.

Right Click Compression

Now when browsing files in Dolphin, right clicking any documents presents a "Compress here" option supporting 7zip 7z along with Zip, Tar and other formats.

Similarly, context menu choices become available for extracting archives dropped into the file manager instantly.

Batch Select Archiving

You can also visually batch select multiple folders and files across Dolphin before hitting "Compress Selection" to package everything together into a 7zip archive using optimal settings automatically.

No command line required. Extraction works similarly via file selection too.

So KDE Plasma users can easily manipulate full blown 7z archives through the convenience of graphical desktop paradigms – while retaining the immense flexibility of 7zip‘s advanced compression and encryption powers under the hood.
