Illumos read versus read/write behavior but it gives you more flexibility in general. However, it's more verbose if you have several netgroups. To see this extra verbosity, consider an Illumos share of 'rwA:B:C,roD:E where all of these are netgroups. Linux, you turn this inside out and wind up writing: @A(rw,.) @B(rw,.) @C(rw,.) @D(ro,.) @E(ro. as far as i know Linux has no way to specify 'any of these n netgroups' in a single match, so you have to have a separate entry for each way netgroup. If you do this a lot you presumably create yourself a superset netgroup, but that doesn't necessarily scale if you're doing this on an ad-hoc basis with various different shares, as we are. The one place where Illumos and Linux are different in an important way for us is remapping or not remapping uid. Illumos supports a 'root' option, where hosts specified in it don't remap uid 0, and this is applied to them separately from whether they have read or read/write permissions. In Linux, uid 0's mapping (or lack of it) is part of a nfs client's options, and so it must be specified together with whether the client has read or read/write permission.
The end results you can get are mostly similar (with one difference that may matter for us someday but Linux gets there in a significantly different way. To simplify a bit, in Illumos you have permissions that apply to things, such as netgroups. If a host would match multiple things, whichever read or read/write permission is listed first takes the priority (more or less). If you write 'rw.,ro. rw permissions take priority for any host in both. In Linux, this is inverted; you have things (aka, nFS clients such as netgroups, that have permissions and other options specified for them. If a host would match multiple netgroups, the first matching one wins and specifies all of the host's permissions and options. This can duplicate the.

Omnios based fileservers to ones based on Linux, i've recently been looking into how to map our current nfs export permissions into, linux's nfs export permissions. As part of this i've been looking into the similarities and differences between the linux model of nfs export permissions and the Illumos one.

Understanding Linux File permissions
To encrypt, ensure that gpg is installed. From there, run the following command: sudo gpg -c ghost-blog-backup. Tar.gz running gpg with the c flag will instantly start the encryption process. When the process finishes, the end result. Now that the backup is encrypted with gpg, its safe to delete the unencrypted Tar archive. To delete it, use the rm command. Tar.gz restore backup Restoring a ghost backup on a new system starts by decrypting the backup. Move g to /home/username/ on the server and decrypt with: gpg g Next, extract the unencrypted archive. Tar.gz Using cd, move the terminal into the sql folder and use the mysqldump command to restore the database.
The next step is to compress these files into a online single tar archive. Creating a tar archive of Ghost makes it much easier to transport backups off of servers, load to places like dropbox, nextCloud, or share with co-workers. To create a new compressed archive of the Ghost backup, use the tar command in terminal. Note: be sure to copy the command exactly. Failing to do so may fail to preserve file permissions during the compression process! Tar.gz encrypt Backup The next step in the backup process is a critical one. Without this step, your Ghost blogs database, critical system files, and more are exposed and accessible to anyone that can access where youve stored the tar archive. Luckily, its very easy to encrypt a tar archive on Linux. The quickest way to encrypt from the linux command line is to use GnuPG.
inside of the Ghost software directory, execute ghost stop to turn off the Ghost software. Ghost stop, with the server software turned off, its safe to make a complete copy of everything to /ghost-blog-backup. Cp -rp /var/www/ghost /ghost-blog-backup, running the. Cp command with the, rP flags will ensure all permissions set by the Ghost installation software stay intact. Cd to move out of /var/www/ghost, and back to /home/username. Cd compress Backup, all of the important Ghost blog files are in /ghost-blog-backup, with their permissions intact.
To restore this type of backup at a later date, go to the same plan url, click Import, browse for the backup and load. Soon after importing, settings and data should be back the way it was when you first backed. Command-line backup, ghost has a decent backup tool built into its software, but it doesnt offer up the same type of security, automation, and freedom that can come from a backup via the linux command line. . to backup a ghost blog on a linux host, create a new folder. This folder will hold all of the important backup files and data pertaining to Ghost. In the server terminal, use the mkdir command to create a new folder. Do not do this as root! Mkdir -p /ghost-blog-backup mkdir -p /ghost-blog-backup/sql, running mkdir creates a new directory in the /home/ folder of the user currently logged. This is a good location to hold backup files, as they wont get lost in random locations on the linux file system.
