Linux OS that has NTFS driver installed, can easily to plug in and plug out NTFS formatted external drives.<\/p>\n
Or look for ntfs-3g driver if NTFS is not supported.<\/p>\n
And can easily be used by both Windows OS and Linux OS.<\/p>\n
This piece of snippet code below will check if a folder exists and execute a command if a folder is found.<\/p>\n
In Linux world, depends on the distro you are using.<\/p>\n
If you insert an NTFS formatted external drive you need to mount the drive.<\/p>\n
Once the external drive is inserted type: df -h<\/p>\n
Then you will have this output or it might be different in your distro.<\/p>\n
\/dev\/sdb1 \u00a0 1.9T<\/p>\n
Then you can proceed to mount the drive like:<\/p>\n
mount -t ntfs \/dev\/sdb1 \/media\/Week1 \u00a0(Week1 is the folder name, can be change to any name)<\/p>\n
Of course there are other methods, if the command above will not work.<\/p>\n
Type “man mount” (don’t include quotes when typing on the terminal) if you want to dig further about mount command.<\/p>\n
For example if you have four drives for Week1 to Week4 rotational backup (monthly backup one drive for each week).<\/p>\n
For readability and clarity purposes, its better to have one folder specific for each week.<\/p>\n
So in \/media or whichever folder you mount the external drives. There will be Week1, Week2, Week3 or Week4 folders.<\/p>\n
Of course backup can be done manually, but it will be awesome and if it could be done automatically.<\/p>\n
Bash script and crontab will come to the rescue.<\/p>\n
For Bash script to check which folder to use, this piece of snippet code below.<\/p>\n
If there are four folders on \/media and each external drive is mounted to an specific folder.<\/p>\n
Once the drive is inserted, Linux OS will automatically activate the mount drive and the mounted folder.<\/p>\n
Here’s the piece of snippet code below:<\/p>\n
======================<\/p>\n
#!\/bin\/sh<\/span> ======================<\/p>\n And you can configure crontab to run the script at a specified date and time.<\/p>\n Type crontab -e and configure the settings as desired.<\/p><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":" Bash Script check if folder exists<\/p>\n This piece of snippet code below will check if a folder exists.<\/p>\n Linux OS that has NTFS driver installed, can easily to plug in and plug out NTFS formatted external drives.<\/p>\n Or look for ntfs-3g driver if NTFS is not supported.<\/p>\n And can easily be used by both Windows […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[47],"tags":[],"_links":{"self":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts\/3233"}],"collection":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3233"}],"version-history":[{"count":1,"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts\/3233\/revisions"}],"predecessor-version":[{"id":3234,"href":"https:\/\/mohan.sg\/index.php?rest_route=\/wp\/v2\/posts\/3233\/revisions\/3234"}],"wp:attachment":[{"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3233"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3233"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mohan.sg\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3233"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
