/home is the only filesystem mounted on Gadi that provides backups. If you accidentally deleted any data in your home folder and want to recover it please follow the example below to copy from the right snapshot.
Every home folder has a hidden directory `.snapshot` in it, even though it won't show up when you list the contents. The folder contains various snapshots of the state of your home directory.
$ ls ~/.snapshot daily.2020-07-03_0010 daily.2020-07-16_0010 hourly.2020-07-16_0205 daily.2020-07-04_0010 hourly.2020-07-15_1405 hourly.2020-07-16_0305 daily.2020-07-05_0010 hourly.2020-07-15_1505 hourly.2020-07-16_0405 daily.2020-07-06_0010 hourly.2020-07-15_1605 hourly.2020-07-16_0505 daily.2020-07-07_0010 hourly.2020-07-15_1705 hourly.2020-07-16_0605 daily.2020-07-08_0010 hourly.2020-07-15_1805 hourly.2020-07-16_0705 daily.2020-07-09_0010 hourly.2020-07-15_1905 hourly.2020-07-16_0805 daily.2020-07-10_0010 hourly.2020-07-15_2005 hourly.2020-07-16_0905 daily.2020-07-11_0010 hourly.2020-07-15_2105 hourly.2020-07-16_1005 daily.2020-07-12_0010 hourly.2020-07-15_2205 hourly.2020-07-16_1105 daily.2020-07-13_0010 hourly.2020-07-15_2305 hourly.2020-07-16_1205 daily.2020-07-14_0010 hourly.2020-07-16_0005 snapmirror.a4b52a78-1197-11ea-9960-00a098f3f6ee_2158894107.2020-07-16_120500 daily.2020-07-15_0010 hourly.2020-07-16_0105 |
Each folder above is a snapshot of your entire $HOME folder at the time shown in the timestamp suffix of the folder name. Choose the closest one to the time you lost the data and copy it back. For example, to copy the lost_folder back to $HOME/recovered_folder, run
$ cp -r ~/.snapshot/hourly.2020-07-16_0805/lost_folder ~/recovered_folder |
It is recommended not to overwrite your existing data in your $HOME folder but please be aware of the disk usage before copying back from the snapshot. The snapshots are not debited to your 10GiB home disk quota but the recovered data is.
To look up the disk usage, run `du`. For example, to look up the usage of the home folder and the folder `lost_folder` in the hourly snapshot captured at 8:05am 16 July 2020, the user abc111 would run
$ cd ~/.snapshot/hourly.2020-07-16_0805/ $ du -sh lost_folder 306M lost_folder $ du -sh $HOME 3.1G /home/111/abc111 |
