After a few recent disasters in our area, we've attached two shares that we are going to use to store backups for 60 days and we'd like to store these as zip files before we move them to these shares. We'd like to automate this task daily after our backup job where we get all of the recent backups, zip them, and copy the zip files to the two shares. How can we do this with PowerShell? In some environments, we will not be able to run an integrity check before backing up the database due to limitations.
Integrity checks should be run as often as we are unable to lose any data — the more important our data are, the more often we need to validate the integrity of our data.
The backup format we use here only serves for demonstration purposes, as we may want to include options with our backup, such as encryption, compression, etc. We also want a regular schedule where we restore backups, to validate times and dates of when we checked their validity while retaining this information.
In the least as a best practice, every backup database should also verify the file is good right after the file has been backed up, which we see in the final step of the above T-SQL.
In the above T-SQL, we save the date and time information with the format of four years, then 2 months, then 2 days. First, we want to mirror this format with the zip file. ToString method and entering the "yyyyMMdd" format in the parentheses. In the first script, the design assumes that we have backups from multiple days in the same folder or location. Since we have multiple backup files in our path and we want the recent wants to copy on to file shares, we will create a file store to copy recent backup files to in order to zip.
The second script will skip this step and assume that all our backups are stored by a folder date eliminating the need to copy recent backup files to a holding folder before compressing. The zip library in. FileSystem class, which has the method CreateFromDirectory requiring two folder paths — one folder path that will be zipped and the other path the actual zip file where it will be saved.
In the first script, we filter the creation date of the files to ensure that we only get the recent backup files. Active Oldest Votes. EXEC master.. Improve this answer. Gulzar Nazim Gulzar Nazim 51k 24 24 gold badges silver badges bronze badges.

If you backup file is over 3Gb in size then compress to a rar file instead of zip. Sign in. United States English. Ask a question. Quick access. Search related threads.
